Variants in MED12 are associated with 3+ intellectual disability syndrome (Lujan-Fryns syndrome, Ohdo syndrome, and Opitz-Kaveggia syndrome are listed in OMIM). The overall phenotype for each syndrome seems to overlap but the criteria used to distinguish between the different syndromes can be different for each paper.
Contractures are most prominent in Opitz-Kaveggia (MIM# 305450) but have also been reported in cases of Ohdo (MIM# 300895) and Lujan-Fryns syndrome (MIM# 309520). Typically associated congenital hypotonia with joint hyperlaxity, progressing to joint contractures.Created: 14 Jul 2021, 11:38 a.m. | Last Modified: 14 Jul 2021, 11:38 a.m.
