Abstract excerpt
Heterozygous variants of MATN3 is one of the common causes of multiple epiphyseal dysplasia (MED). Here we report three individuals from two unrelated families who harbor compound heterozygous variants in MATN3 (p.Arg121Trp and p.Val220Ala). Contrary to the MED phenotype, these individuals exhibit spondyloepimetaphyseal dysplasia (SEMD) resembling the phenotypes caused by homozygous MATN3 variants. Clinical...
