Chromocenters consist of clustered pericentromeric heterochromatin and contain telomere sequences. Indirect immunofluorescence revealed a partial colocalization of GFP-SALL1 with M31, the mouse homolog of the Drosophila heterochromatic protein HP1 (CBX5; <a href="/entry/604478">604478</a>). SALL1 acted as a strong transcriptional repressor which could not be relieved by the addition of the histone deacetylase inhibitor trichostatin A. Using a yeast 2-hybrid screen, PIN2, an isoform of telomere repeat-binding factor 1 (TERF1; <a href="/entry/600951">600951</a>), was identified as an interaction partner of SALL1. The interaction was confirmed in vitro in a GST pull-down assay.

TBS is a rare, autosomal dominant malformation syndrome with a combination of anal, renal, limb, and ear anomalies. They demonstrated SALL1 mutations in a family with 3 cases of TBS in 2 generations (<a href="#0001">602218.0001</a>) and in an unrelated family with a sporadic case of TBS (<a href="#0002">602218.0002</a>).

The patient had a relatively mild phenotype, with 1 limb affected by preaxial polydactyly and a triphalangeal thumb. The mutation was found to undergo nonsense-mediated decay, which the authors postulated may have accounted for the relatively mild phenotype by eliminating a possible dominant-negative effect.

<p>The region-specific homeotic gene spalt (sal) of Drosophila is an essential genetic component required for the specification of posterior head and anterior tail as opposed to trunk segments. Sal encodes a protein that contains 3 distinct DNA-binding zinc finger domains and alanine- and glutamine-rich domains that are commonly found in transcription factors (Kohlhase et al., 1996) </p>

<p>Kohlhase et al. (1996) used the unusual but characteristic structure of sal to isolate sal-like genes from humans. The SALL1 gene encodes a putative protein of 1,306 amino acids. Kohlhase et al. (1996) used Northern blot analysis to show that the SALL1 gene is expressed in a subset of human tissues, with highest expression in kidney, brain, and liver. They showed by in situ hybridization that SALL1 and SALL2 (602219) are expressed in different areas of the fetal brain, probably in distinct sets of neurons. </p>

<strong>Gene Function</strong>

<span class="mim-text-font">
<p>Netzer et al. (2001) used epifluorescence and confocal microscopy to localize a GFP-SALL1 fusion protein to chromocenters and smaller heterochromatin foci in transiently transfected NIH 3T3 cells. Chromocenters consist of clustered pericentromeric heterochromatin and contain telomere sequences. Indirect immunofluorescence revealed a partial colocalization of GFP-SALL1 with M31, the mouse homolog of the Drosophila heterochromatic protein HP1 (CBX5; 604478). SALL1 acted as a strong transcriptional repressor which could not be relieved by the addition of the histone deacetylase inhibitor trichostatin A. Using a yeast 2-hybrid screen, PIN2, an isoform of telomere repeat-binding factor 1 (TERF1; 600951), was identified as an interaction partner of SALL1. The interaction was confirmed in vitro in a GST pull-down assay. The authors proposed an involvement of SALL1 in the regulation of higher order chromatin structures and hypothesized that the protein may be a component of a distinct heterochromatin-dependent silencing process. </p><p>Using gel retardation assays, reporter gene assays, and mutation analysis, Chai et al. (2006) showed that SIX1 (601205) directly bound the SALL1 promoter and induced SALL1 expression in a dose-dependent manner. </p><p><strong><em>Truncated SALL1</em></strong></p><p>
Bozal-Basterra et al. (2018) showed that primary fibroblasts derived from Townes-Brocks syndrome (TBS; 107480) patients exhibit changes in SALL1 localization, a higher rate of ciliogenesis, abnormally elongated cilia, aberrant cilia disassembly, and SHH (600725) signaling defects. Through proximity proteomics, Bozal-Basterra et al. (2018) identified 2 main ciliogenesis suppressors, CCP110 (609544) and CEP97 (615864), as interactors of TBS-causing truncated SALL1. The higher rate of ciliogenesis detected in TBS-derived primary fibroblasts is consistent with an observed lower amount of CCP110 and CEP97 at the mother centriole in these fibroblasts compared with controls. Bozal-Basterra et al. (2018) noted that truncated SALL1, alone or with full-length SALL1, sequesters CCP110 and CEP97, disrupting cilia formation and function. </p>

<span class="mim-text-font">
<p>The expression patterns of sal-like genes in mouse, Xenopus, and the fish Medaka, and the finding that Medaka sal is regulated by Sonic hedgehog (600725), prompted Kohlhase et al. (1998) to examine SALL1 as a candidate gene for Townes-Brocks syndrome (TBS; 107480). TBS is a rare, autosomal dominant malformation syndrome with a combination of anal, renal, limb, and ear anomalies. They demonstrated SALL1 mutations in a family with 3 cases of TBS in 2 generations (602218.0001) and in an unrelated family with a sporadic case of TBS (602218.0002). Both mutations were predicted to result in a prematurely SALL1 protein lacking all putative DNA-binding domains. TBS therefore represents another human developmental disorder caused by mutations in a putative C2H2 zinc finger transcription factor. </p><p>To determine the spectrum of SALL1 mutations in TBS and to investigate the genotype-phenotype correlations, Kohlhase et al. (1999) examined 23 additional families with TBS or similar phenotypes for SALL1 mutations. In 9 of the families, mutations were identified. None of the mutations had previously been described. Two of the mutations were nonsense mutations, 1 of which occurred in 3 unrelated families (602218.0003). Five of the mutations were short deletions. All of the mutations were located 5-prime of the first double zinc finger (DZF)-encoding region and were therefore predicted to result in prematurely terminated proteins lacking all DZF domains. This suggested that only those SALL1 mutations that remove the DZF domains result in TBS. Kohlhase et al. (1999) also presented evidence that in rare cases SALL1 mutations can lead to phenotypes similar to Goldenhar syndrome (164210); see 602218.0005. On the whole, however, phenotypic differences in TBS did not seem to depend on the site of the mutation within the gene. </p><p>Marlin et al. (1999) searched for SALL1 mutations in 11 unrelated individuals with TBS (5 familial and 6 sporadic) and detected a mutation in 9 of them. One nonsense and 6 different novel frameshift mutations, all located in the second exon, were identified. Together with the previously reported mutations, the new information established that TBS results from haploinsufficiency. The finding of de novo mutations in the sporadic cases was consistent with the proposed complete penetrance of the disorder. Moreover, the occurrence of the same 826C-T transition in a CG dimer, in 3 sporadic cases from the present series and 3 sporadic cases from the series of Kohlhase et al. (1999), representing 6 of the 8 mutations identified in sporadic cases, revealed the existence of a mutation hotspot. </p><p>The occurrence of a balanced translocation t(5;16)(p15.3;q12.1) in a child with Townes-Brocks syndrome had permitted assignment of the causative gene to 16q12.1 (Serville et al., 1993). Marlin et al. (1999) found no modification of the SALL1 gene in this patient. Further studies indicated that the breakpoint was at least 180 kb telomeric to SALL1, thus indicating that a position effect underlay the disease in this patient. </p><p>Kohlhase (2000) stated that 19 of the 20 known SALL1 mutations were located in exon 2, 5-prime of the third double zinc finger-encoding region. These are nonsense mutations, short insertions, and short deletions, as well as 1 gross intraexonic deletion. One mutation within intron 2 created an aberrant splice site. Most mutations led to preterminal stop codons and were thought to cause the phenotype of Townes-Brocks syndrome via haploinsufficiency. However, one short deletion resulted in a phenotype different from TBS and may have been produced by a dominant-negative effect of a truncated SALL1 protein. </p><p>In a father and 2 daughters with a disorder showing phenotypic overlap between Townes-Brocks syndrome (107480) and branchiootorenal dysplasia (113650), Engels et al. (2000) identified a mutation in the SALL1 gene (602218.0007). </p><p>Keegan et al. (2001) analyzed the SALL1 gene in 4 patients with hemifacial microsomia-expanded spectrum and anal anomalies (see 164210) and identified the R276X mutation (602218.0003) in 1 patient. The authors suggested that patients with overlapping features of both Townes-Brock syndrome and hemifacial microsomia-expanded spectrum should be screened for SALL1 mutations. </p><p>In 3 members of a nonconsanguineous German family who exhibited only some features of Townes-Brocks syndrome (see 107480), with intrafamilial variation, Albrecht et al. (2004) identified a mutation in the SALL1 gene (602218.0009). </p><p>Botzenhart et al. (2005) stated that 35 mutations had been identified in the SALL1 gene. Most mutations occur 5-prime to or within the region encoding the first double zinc finger. </p><p>Bohm et al. (2006) traced the parental origin of SALL1 mutations in sporadic TBS by analysis of linkage between SALL1 mutations and exonic or intronic polymorphisms in 16 families with 10 different mutations. Mutations were of paternal origin in 14 (87.5%) of 16 cases, independent of mutation type and with no obvious paternal age effect. </p><p>Kosaki et al. (2007) analyzed the SALL1 gene in 2 sisters, 1 with a Townes-Brocks syndrome phenotype and the other exhibiting some features of Goldenhar syndrome (164210), and identified heterozygosity for a mutation (L419X; 602218.0010). Their mother, who had dysplastic external ears but was otherwise normal, also carried the mutation. </p>

<p>Si Dong et al. (2003) examined the effect of losing both of the spalt genes (spalt and spalt-related) in the Drosophila melanogaster, and reported defects similar to those in humans with Townes-Brocks syndrome. Loss of both spalt and spalt-related function in flies yielded morphologic defects in the testes, genitalia, and antenna. Furthermore, spalt/spalt-related mutant antennae showed severe reduction in Johnston's organ, the major auditory organ in Drosophila. Electrophysiologic analyses confirmed that spalt/spalt-related mutant flies are deaf. These commonalities suggested that there is functional conservatism for spalt genes between vertebrates and insects. </p><p>Mutations in SALL1 have been postulated to cause TBS by haploinsufficiency; however, Nishinakamura et al. (2001) reported a mouse model carrying a Sall1 null allele which did not mimic the human syndrome. Kiefer et al. (2003) created a mutant murine Sall1 allele that produced a truncated protein and recapitulated the abnormalities found in human TBS. Heterozygous mice mimicked TBS patients by displaying high-frequency sensorineural hearing loss, renal cystic hypoplasia, and wrist bone abnormalities. Homozygous mutant mice exhibited more severe defects than Sall1 null mice, including complete renal agenesis, exencephaly, and limb and anal deformities. Truncated Sall1 mediated interaction with all Sall family members and could therefore interfere with the normal function of all Sall proteins. The authors proposed a model for the pathogenesis of TBS in which expression of truncated SALL1 protein causes abnormal development of multiple organs, either due to dominant-negative or gain-of-function activity of the mutant protein. </p><p>In Sall1-mutant transgenic mice, Kiefer et al. (2008) showed that mutant Sall1 protein alone is sufficient to cause limb phenotypes that are characteristic of TBS patients. Using a B-cell line from a patient with the R276X mutation, the authors demonstrated expression of truncated SALL1 protein, indicating that the same pathogenetic mechanism occurs in humans. Kiefer et al. (2008) also found that TBS mutant protein is capable of dominant-negative activity that results in ectopic activation of 2 downstream genes, Nppa (108780) and Shox2 (602504), in the developing mouse heart and limb, and proposed a model for TBS pathogenesis in which truncated SALL1 protein causes derepression of SALL-responsive target genes. </p>

<p>Engels et al. (2000) described a father and his 2 affected daughters who had phenotypic features which overlapped those of Townes-Brocks syndrome (107480) and branchiootorenal syndrome (113650). A heterozygous 1-bp deletion was found at nucleotide 1819 in exon 2 of the SALL1 gene between the coding regions for the first and second double zinc finger unit. Engels et al. (2000) proposed that this mutation may result in a truncated protein rather than an unstable mRNA, causing the variant phenotype seen in these patients. The daughters had dysplastic ears, hypoplastic kidneys with impaired renal function, gastroesophageal reflux, hypermetropia, and mild developmental delay. The father showed impaired renal function, dysplastic ears, and gastroesophageal reflux. The affected individuals lacked abnormalities of the anus or thumbs. </p>

(2004) identified a heterozygous 967C-T transition, resulting in a gln323-to-ter substitution (Q323X) that predicts a prematurely terminated protein lacking all double zinc finger domains or no protein at all. Characteristic features of TBS included preauricular tags, overfolded helices, hypospadias, and impaired renal function; 1 brother had only hypospadias and underriding third toes. None of the affected family members had the characteristic anal or hand malformations of TBS. Albrecht et al.

The patient had bilateral preaxial polydactyly, imperforate anus, rectal atresia, hypospadias, and overfolded helices. The mutation was found to be resistant to nonsense-mediated decay. Furniss et al. (2007) concluded that the phenotype was caused by a truncated SALL1 protein acting in a dominant-negative manner. These findings were in contrast to another SALL1 mutation (602218.0012) that did undergo nonsense-mediated decay and was associated with a milder phenotype. </p>

To ensure long-term funding for the OMIM project, we have diversified
our revenue stream. We are determined to keep this website freely
accessible. Unfortunately, it is not free to produce. Expert curators
review the literature and organize it to facilitate your work. Over 90%
of the OMIM's operating expenses go to salary support for MD and PhD
science writers and biocurators. Please join your colleagues by making a
donation now and again in the future. Donations are an important
component of our efforts to ensure long-term funding to provide you the
information that you need at your fingertips.
