Presentation
Carpal and tarsal synostoses are present. The average height of affected male adults was 152 cm. This medical entity is very similar to the mesomelia-synostosis syndrome. [accessanesthesiology.mhmedical.com]
MSS patients may present with complex congenital heart defects, congenital hydronephrosis, unusual skin coverage on the umbilical cord stump, myopia, short sublingual frenulum and progressive hearing loss. Cognitive development is normal. [orpha.net]

Diagnostic methods Diagnosis is suspected on the basis of clinical and radiological findings and is confirmed by cytogenetic analysis (array CGH, FISH). [orpha.net]
- Short Stature
First described in 1995 as a newly autosomal dominant inherited form of mesomelic shortness of stature by A Verloes and A David. Autosomal dominant; two families described. [accessanesthesiology.mhmedical.com]
Both rhizomelic and mesomelic dysplasia and short stature may be encountered in the same patient [1]. [link.springer.com]

Etiology
Etiology MSS is due to a non-recurrent microdeletion in 8q13. All patients have a deletion of two contiguous genes: SULF1 and SLCO5A1. Reported deletion sizes vary from 582Kb to 738 Kb. MSS is likely to represent a contiguous gene deletion syndrome. [orpha.net]
