Abstract
Aarskog-Scott syndrome (ASS) is a rare X-linked recessive genetic disorder caused by FGD1 mutations. FGD1 regulates the actin cytoskeleton and regulates cell growth and differentiation by activating the c-Jun N-terminal kinase signaling cascade. ASS is characterized by craniofacial dysmorphism, short stature, interdigital webbing and shawl scrotum. However, there is a wide phenotypic heterogeneity because of the additional clinical features. ASS and some syndromes including the autosomal dominant inherited form of Robinow syndrome, Noonan syndrome, pseudohypoparathyroidism, Silver-Russel and SHORT syndrome have some overlapping phenotypic features. Herein, we report a patient with ASS and a large anterior fontanel who was initially diagnosed as Robinow syndrome. He was found to have a novel c.1340+2 T>A splice site mutation on the FGD1 gene.
