| The mildest form of otopalatodigital syndrome spectrum disorder, characterized by a generalized skeletal dysplasia, mild intellectual disability, conductive hearing loss, and typical facial anomalies. Caused by gain of function mutations in the gene FLNA (Xq28) that encodes filamin A. Inherited in an X-linked dominant manner. Male-to-male transmission has not been reported. The chance of transmitting the mutation in each pregnancy is 50%; males inheriting the mutation will be affected while females who inherit the mutation have a broad range of phenotypic expression. |
