Rebecca Foulger (Genomics England curator)

PMID:26463574 report 2 unrelated families with phenotypes including microcephaly and developmental delay in both probands, and homozygous mutations (1 frameshift, 1 missense) in DIAPH1.
Created: 2 Mar 2017, 4:55 p.m.
PMID:24781755 report a consanguineous Saudi Arabian pedigree with a novel syndromic form of MCP, involving small head size, ID, seizures, short stature, and blindness. They identified a nonsense homozygous DIAPH1 variant (c.2332C>T, Q778*) in the family. The presence of the heterozygous sequence variant in both parents was confirmed.
Created: 2 Mar 2017, 4:54 p.m.
Comment on list classification: Updated rating from Red to Green: 3 unrelated cases of homozygous DIAPH1 variants and microcephaly + intellectual disability/developmental delay.
Created: 2 Mar 2017, 4:54 p.m.
