Description

DNA sequence analysis of the PTEN gene demonstrated a sequence change, c.764T>A, in exon 7 that results in an amino acid change, p.Val255Glu. This sequence change is absent from known population databases (gnomAD). The p.Val255Glu change affects a moderately conserved amino acid residue located in a domain of the PTEN protein that is known to be functional. The p.Val255Glu substitution appears to be damaging using several in-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL). This sequence change has been identified in one individual with a mild presentation of macrocephaly (PMID: 23361946). Extensive functional studies have demonstrated that p.Val255Glu disrupts protein function (PMIDs: 29785012, 29706350, 10555148). Based on the available evidence, this sequence change is likely pathogenic.
