<span class="mim-text-font">
<p>Mucopolysaccharidosis type IVB (MPS4B) is an autosomal recessive disorder characterized by skeletal dysplasia and corneal clouding. There is no central nervous system involvement and intelligence is normal. There is increased urinary keratan sulfate excretion (Suzuki et al., 2001).</p><p>See mucopolysaccharidosis type IVA (MPS4A; 253000), also known as Morquio syndrome A, a genetically distinct disorder with overlapping clinical features caused by mutation in the GALNS gene (612222) on chromosome 16q24.</p><p>There may also be a nonkeratan sulfate-excreting form of Morquio syndrome, so-called type C (252300).</p>

<strong>Clinical Features</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>O'Brien et al. (1976) reported a 14-year-old girl with spondyloepiphyseal dysplasia, corneal clouding, and beta-galactosidase deficiency. Radiographic features included flattening of the vertebral bodies and femoral heads, coxa valga, abnormal metacarpal epiphyses, and narrowed phalanges. Beta-galactosidase activity was less than 5% of normal and both unaffected parents had about 50% residual enzyme activity. She had no neurologic abnormalities, which distinguished the disorder from GM1-galactosidase types I and II (230500, 230600). </p><p>Arbisser et al. (1977) reported another 14-year-old girl with mild dysostosis multiplex, odontoid hypoplasia, short stature, cloudy corneas, and increased urinary keratan sulfate, but no detectable central nervous system abnormalities. At age 9 years, she had shown kyphosis, swinging gait, and hip pain. The increased keratan sulfate suggested Morquio syndrome A, but galactosamine-6-sulfate sulfatase (GALNS) activity was normal, and beta-galactosidase activity was decreased. Conjunctival biopsy showed intracytoplasmic vacuoles typical of a lysosomal storage disease. The patient's mother showed an intermediate level of beta-galactosidase; the father was not available for study. Arbisser et al. (1977) postulated that the deficiency of beta-galactosidase in this patient was responsible for inadequate degradation of keratan sulfate and the appearance of a milder form of the Morquio syndrome. The authors suggested the designation Morquio syndrome B (MPS IVB) to differentiate it from classic Morquio syndrome A. </p><p>Spranger (1977) commented that the 'unusual' form of Morquio syndrome described by Dale (1931) was similar to that described by Arbisser et al. (1977) and thus likely represented beta-galactosidase deficiency. Spranger (1977) also noted that failure to detect heparan sulfate activity in some patients may be due to technical problems or residual enzyme activity. </p><p>Groebe et al. (1980) reported 2 cases of Morquio syndrome due to beta-galactosidase deficiency. That beta-galactosidase was indeed the primary defect was indicated by the absence of an endogenous inhibitor and by the intermediate enzyme levels in parents. </p><p>Van Gemund et al. (1983) reported 3 Dutch sibs, born of consanguineous parents, with Morquio syndrome B and beta-galactosidase deficiency. Clinical features included dysplastic hip joints, thoracolumbar kyphosis, protruding sternum, progressive short stature, and corneal opacities. Radiographic studies showed platyspondyly with abnormal vertebral bodies. </p><p>Beck et al. (1987) described 3 sibs with Morquio syndrome B. They had short trunk dwarfism, dysplasia of the pelvis, and epiphyseal abnormalities. Intelligence was normal. All had profound deficiency of beta-galactosidase activity in cultured fibroblasts. </p><p>Giugliani et al. (1987) described a brother-sister pair with clinical, radiologic, and enzymatic evidence of Morquio syndrome B but with atypical mental regression. There were also some atypical properties of the residual beta-galactosidase activity. Giugliani et al. (1987) suggested that these findings indicated that further heterogeneity can result from mutation at the beta-galactosidase locus. </p><p>Caciotti et al. (2021) reported 9 patients, aged 5 to 54 years, with MPS IVB. The major clinical features in this cohort included dysostosis multiplex, genu valgus, short stature, and mildly coarse facies. Other features included mild mitral and/or tricuspid regurgitation in 5 patients, corneal clouding in 2, and mild hepatosplenomegaly in 2. Brain MRI was reported in 5 patients, and 2 had a thin corpus callosum. </p>

<strong>Biochemical Features</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>Van der Horst et al. (1983) showed that fibroblasts from patients with Morquio syndrome B contained normal numbers of beta-galactosidase molecules with a normal turnover, but strongly reduced catalytic activity per enzyme molecule. Abnormal affinity for several substrates was found, including no detectable affinity for keratan sulfate and oligosaccharides. In contrast, these affinities were normal for the beta-galactosidase in adult type GM1-gangliosidosis fibroblasts (230650). Cell hybridization studies demonstrated that MPS IVB and the infantile and adult forms of GM1-gangliosidosis belong to the same complementation group. </p><p>Caciotti et al. (2021) reported biochemical findings in 9 patients with MPS IVB. Total glycosaminoglycans were elevated in the urine of 3 of 7 patients. Qualitative glycosaminoglycan analysis in urine did not show elevated keratan sulfate in any of the patients, but LC-MS/MS analysis in urine of 7 patients showed elevated levels of keratan sulfate in all 7. Urine disulfated disaccharides were significantly higher in patients with Morquio syndrome type A (253000) compared to patients with MPS IVB, and both values were higher than in controls. </p>

<strong>Molecular Genetics</strong>

<span class="mim-text-font">
<p>In 3 patients with Morquio syndrome B, Oshima et al. (1991) identified 3 different compound heterozygous mutations in the GLB1 gene (611458.0009-611458.0011). </p><p>In a 15-year-old Japanese boy who presented with Morquio syndrome B, Ishii et al. (1995) found compound heterozygosity for 2 mutations in the GLB1 gene (Y83H, 611458.0015 and R482C, 611458.0016). </p><p>In a French patient with Morquio syndrome B phenotype, Paschke et al. (2001) identified compound heterozygosity for 2 mutations in the GLB1 gene: T500A (611458.0020) and Q408P (611458.0021). </p><p>Caciotti et al. (2021) reported the GLB1 mutations in 9 patients, including 2 sib pairs, with MPS IVB. The mutations were identified by Sanger sequencing of the gene. Heterozygosity for the W273L mutation (611458.0009) was identified in 7 patients. Three novel mutations were identified, including a splicing mutation (611458.0027) and 2 missense mutations, V677G (611458.0028) and Y192C. In 1 patient (patient 7), only a single mutation (W273L) was identified; however, a potential splicing defect excluding exons 2-7 was identified in this patient, leading Caciotti et al. (2021) to hypothesize that a deep intronic mutation was also present. </p>

<strong>Genotype/Phenotype Correlations</strong>

</h4>
</div>
<span class="mim-text-font">
<p>Hinek et al. (2000) performed functional expression studies on several GLB1 mutations resulting in Morquio syndrome B (see, e.g., G438E, 611458.0018; T500A; W273L, 611458.0009; and R482H, 611458.0010). All of the mutations were located in the coding region common to the GLB1 lysosomal enzyme and its splice variant S-Gal/EBP (elastin-binding protein), and none of the mutant proteins expressed EBP. Functional studies indicated that the mutant proteins resulted in impaired secretion of tropoelastin and inability to assemble elastic fibers, resulting in impaired elastogenesis. </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.
