Metatropic dysplasia: clinical and molecular diagnostics, genetic counseling

Metatropic dysplasia (MTD; OMIM #156530) is a rare spondyloepimetaphyseal dysplasia with autosomal dominant inheritance. Here we present the results of the clinical, radiological and molecular genetic diagnosis of MTD in a circassian girl with novel de novo p.Pro82Leu (NG_017090.1:g.23856C>T, c.245C>T) mutation in exon 1 of the TRPV4 gene. Considering gonadal mosaicism prenatal diagnosis in MTD families for the next pregnancies is recommended.
