| A very rare X-linked multisystem genetic disease characterized by intellectual disability, truncal obesity, gynecomastia, hypogonadism, dysmorphic facial features, and short stature. The syndrome has been described in two families to date. The syndrome has been linked to a mutation in the consensus donor splice site of the histone deacetylase 8 HDAC8 gene (Xq13). X-linked recessive transmission and X-linked dominant inheritance with absence of male-to-male transmission have been reported. |
