MedGen UID:: 337461
•Concept ID:: C1845902
•: Disease or Syndrome

Although the phenotypic spectrum and severity of FG syndrome is wide, the cardinal features include congenital hypotonia, delayed speech development, relative macrocephaly, dysmorphic facies, and anal anomalies or severe constipation (Unger et al., 2007). For a general phenotypic description and a discussion of genetic heterogeneity of FG syndrome, see FGS1 (305450).
