Prepregnancy plasma cholesterol levels were similar between wildtype and Bpa1H/+ dams fed a standard, cholesterol-free diet. However, there was a marked decrease in cholesterol levels between embryonic day (E) 8.5 and E10.5 for both genotypes. There was a significant lag between E11.5 and E13.5 (p = 0.0011) in the recovery of levels in Bpa1H/+ dams to their prepregnancy values. The authors generated transgenic mice that expressed human NSDHL and rescued the male lethality of the Bpa1H null allele. In Bpa1H/+ female embryos where the mutant X chromosome was transmitted from a heterozygous mother or a rescued mutant father, placental areas at E10.5 were 50% less than wildtype. Expression of Nsdhl in trophoblast lineages of the placenta and yolk sac endoderm (which occur only from the maternally inherited allele in a female embryo) had the largest effect on placental area (p less than 0.0001).

(2010)</a> identified a hemizygous 3-bp deletion (696delGAA) in exon 7 of the NSDHL gene, resulting in the deletion of residue lys232, which was predicted to disrupt the beta-pleated sheet. The phenotype was characterized by mild to severe mental retardation, infantile seizures, thin body habitus, dysmorphic facial features, and polymicrogyria/pachygyria. Studies in patient cells, HEK293 cells, and yeast cells indicated that the mutant protein was temperature-sensitive: at 30 degrees Celsius, the protein was expressed, folded, localized, and functioned correctly, but at 37 degrees, the protein was improperly folded and degraded, resulting in a loss of function. Affected males and obligate female carriers had normal plasma cholesterol, steroid hormone levels, and lipoprotein profiles, but cultured lymphoblastoid cells expressing the mutation showed sterol aberrations, such as accumulation of 4-methyl sterol intermediates, 4,4-dimethyl sterol intermediates, lathosterol, and desmosterol. Cerebrospinal fluid from an affected individual also showed increased methylsterol levels. <a href="#13" class="mim-tip-reference" title="McLarren, K. W., Severson, T. M., du Souich, C., Stockton, D.

<p>Caldas and Herman (2003) investigated the subcellular localization of wildtype and mutant murine Nsdhl proteins in transfected COS-7 cells using confocal microscopy. In addition to endoplasmic reticulum (ER)- localization commonly found for enzymes of post-squalene cholesterol biosynthesis, the authors identified a novel association of NSDHL with lipid droplets, which are ER-derived cytoplasmic structures containing a neutral lipid core. Trafficking through the Golgi was necessary for ER membrane localization of the protein. </p>

<p><strong><em>CHILD Syndrome</em></strong></p><p>
Konig et al. (2000) analyzed 6 patients with CHILD syndrome (308050) for mutations in the NSDHL gene and in the EBP gene (300205), which functions downstream of NSDHL in a later step of cholesterol biosynthesis. Four of the cases were sporadic, including one in a previously reported 46,XY male (Happle et al., 1996), and 2 were familial cases in a mother and her daughter. No mutations were identified in the EBP gene; however, mutations were identified in the NSDHL gene in all of the patients. The NSDHL mutations included 2 missense mutations (300275.0001-300275.0002) and 2 nonsense mutations (300275.0003-300275.0004). One of these mutations was found in both the mother and daughter and in another patient, although based on their family history and ethnic background, they were highly unlikely to be related. The authors concluded that CHILD syndrome can be added to the list of developmental defects associated with mutations affecting cholesterol synthesis. </p><p>In a 37-year-old female with CHILD syndrome including torsional and angular deformities of the limbs, Martinez et al. (2022) reported a novel 3-basepair deletion in the NSDHL gene (c.896_898del), resulting in deletion of the amino acid valine at position 299 (val299del). </p><p><strong><em>CK Syndrome</em></strong></p><p>
CK syndrome (300831) is an X-linked recessive mental retardation syndrome associated with seizures, thin body habitus, and cortical malformations. Only males are affected; carrier females are unaffected. In affected members of the original family with CK syndrome reported by du Souich et al. (2009), McLarren et al. (2010) identified a hemizygous mutation in the NSDHL gene (300275.0008). A second affected family, originally reported by Tarpey et al. (2009), was found to have a different mutation (300275.0008). In vitro functional expression studies by McLarren et al. (2010) showed that both mutations acted as temperature-sensitive hypomorphic alleles, resulting in a less severe phenotype than that observed with mutations causing CHILD syndrome. McLarren et al. (2010) suggested that the CK syndrome phenotype resulted mainly from accumulation of toxic methylsterol, not necessarily from cholesterol deficiency. </p><p><strong><em>Associations Pending Confirmation</em></strong></p><p>

<p>Angel et al. (1993) mapped the 'bare patches' (Bpa) and 'striated' (Str) mouse mutations, which behave as X-linked dominant male-lethal mutations, to a region of the X chromosome homologous to human Xq28. Levin et al. (1996) defined several candidate genes in this interval. Liu et al. (1999) reported mutations in one of these genes, Nsdhl, encoding an NAD(P)H steroid dehydrogenase-like protein, in 2 independent Bpa and 3 independent Str alleles. Quantitative analysis of sterols from tissues of affected Bpa mice supported a role for Nsdhl in cholesterol biosynthesis. The results demonstrated that Bpa and Str are allelic mutations and identified the first mammalian locus associated with an X-linked dominant, male-lethal phenotype. </p><p>Mutant male embryos for several Nsdhl alleles die in midgestation with placental insufficiency. Cunningham et al. (2010) examined a role of the maternal genotype in such placental pathology. Prepregnancy plasma cholesterol levels were similar between wildtype and Bpa1H/+ dams fed a standard, cholesterol-free diet. However, there was a marked decrease in cholesterol levels between embryonic day (E) 8.5 and E10.5 for both genotypes. There was a significant lag between E11.5 and E13.5 (p = 0.0011) in the recovery of levels in Bpa1H/+ dams to their prepregnancy values. The authors generated transgenic mice that expressed human NSDHL and rescued the male lethality of the Bpa1H null allele. In Bpa1H/+ female embryos where the mutant X chromosome was transmitted from a heterozygous mother or a rescued mutant father, placental areas at E10.5 were 50% less than wildtype. Expression of Nsdhl in trophoblast lineages of the placenta and yolk sac endoderm (which occur only from the maternally inherited allele in a female embryo) had the largest effect on placental area (p less than 0.0001). The maternal genotype had a smaller effect, independent of the fetal genotype (p = 0.024). Cunningham et al. (2010) concluded that there are significant effects of the mother and fetal membranes on pregnancy outcome, and implicated a role for cholesterol homeostasis during human pregnancy. </p><p>McLarren et al. (2010) found expression of the NSDHL gene in developing cortical neurons and glia in both human and mouse. Embryonic forebrains from male mice with a loss-of-function Nsdhl allele showed a thin and disorganized cortex with increased numbers of apoptotic cells and decreased cellular proliferation. </p>

Affected males and obligate female carriers had normal plasma cholesterol, steroid hormone levels, and lipoprotein profiles, but cultured lymphoblastoid cells expressing the mutation showed sterol aberrations, such as accumulation of 4-methyl sterol intermediates, 4,4-dimethyl sterol intermediates, lathosterol, and desmosterol.

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.
