Additional Information:

Description: (OMIM) Otopalatodigital syndrome-1 is 1 of 4 otopalatodigital syndromes caused by mutations in the FLNA gene. The disorders, which include frontometaphyseal dysplasia (FMD; 305620), otopalatodigital syndrome-2 (OPD2; 304120), and Melnick-Needles syndrome (MNS; 309350), constitute a phenotypic spectrum. At the ...
Clinical Description OMIM Dudding et al. (1967) described 3 male sibs with conduction deafness, cleft palate, characteristic facies, and a generalized bone dysplasia. A broad nasal root gives the patient a pugilistic appearance. Wide-spacing of the toes creates a resemblance to ...
Molecular genetics OMIM Robertson et al. (2003) demonstrated that OPD1 is caused by gain-of-function mutations in the gene encoding filamin A (FLNA; 300017). They also demonstrated FLNA mutations in OPD2.
