Description

The c.350delC variant in PAH has been previously reported in at least 2 Arab-Israeli probands with classic PKU (PMID: 18299955; PMID: 18294361); BH4 deficiency was not excluded (PP4). The variant is a frameshift variant occurring in exon 3 of 13 in the canonical transcript of PAH, a gene fulfilling the most recent criteria for LOF being a known disease mechanism (PVS1; see PVS1: Recommendations for Interpreting the Loss of Function PVS1 ACMG/AMP Variant Criteria). It is absent from control databases including ethnically matched individuals, including gnomAD/ExAC, 1000 Genomes, and the Greater Middle East Variome (PM2).
