Is Femoral facial syndrome inherited ?
Is femoral facial syndrome inherited? The vast majority of cases of femoral facial syndrome (FFS) have been sporadic, not inherited. When a condition is sporadic, it means that it occurs in an individual who has no history of the condition in his/her family. Occurrence in more than one family member has been reported in three cases, but no sibling recurrences have been reported. Maternal diabetes has been recognized as a major factor causing FFS in more than 20% of the reported cases. The circumstances of the reported cases in the literature support non-genetic causes of FFS, such as teratogenic exposure. It is theoretically possible that the cause could sometimes be a new gene mutation occurring in the affected individual, or autosomal dominant inheritance with reduced penetrance.
