Description

In 2 unrelated children with Turnpenny-Fry syndrome (TPFS; 618371), the Deciphering Developmental Disorders Study (2015) identified heterozygosity for a G-to-A transition (chr17.36,895,854G-A, GRCh37) in the PCGF2 gene, resulting in a pro65-to-leu (P65L) substitution. The mutation arose de novo in both patients. Functional studies were not reported.

In 9 unrelated children with Turnpenny-Fry syndrome, Turnpenny et al. (2018) identified heterozygosity for a c.194C-T transition in the PCGF2 gene, resulting in the previously reported pro65-to-leu substitution at a highly conserved residue located just after the N-terminal RING finger motif. In 8 of the patients, the mutation arose de novo; however, in a 9-year-old girl (patient 11), the mutation was inherited from her asymptomatic mother, who was found to be mosaic (21% in blood DNA). Functional studies were not reported.
