RCV000993597 | SCV001146688 | pathogenic | Phenylketonuria | 2019-02-26 | reviewed by expert panel | curation | The PAH: c.47_48dupCT variant is a frameshift variant occurring in exon 1 of 13 in the canonical transcript of PAH, a gene fulfilling the most recent criteria for LOF being a known disease mechanism (see PMID: 30192042) (PVS1). The variant has been previously reported in trans with the known pathogenic L48S allele in 1 Israeli case with classic PKU (PMID: 18299955; PMID: 18294361) as assessed by plasma Phe levels; BH4 deficiency was excluded. It was also noted in 3 Turkish probands: in two, it was found in trans with the p.R243X allele, and in one, it was found in trans with the p.R261Q allele (PMID: 21147011); all three cases had classic as assessed by plasma Phe levels and BH4 deficiency was excluded by genetic testing. Thus PM3_Strong and PP4_Moderate apply. It is absent from control databases including ethnically matched individuals, including gnomAD/ExAC, 1000 Genomes, and ESP (PM2). |
