Variant summary
Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BP4BA1
This summary comes from the ClinGen Evidence Repository: PAH-specific ACMG/AMP criteria applied: BA1: Highest MAF=0.10514 in 1000G. 35 homozygotes in ExAC; BP4: HSF: No significant splicing motif alteration detected. This mutation has probably no impact on splicing. CADD=1.163344. In summary this variant meets criteria to be classified as benign for phenylketonuria in an autosomal recessive manner based on the ACMG/AMP criteria applied as specified by the PAH Expert Panel: (BA1, BP4).

Variant summary: c.707-7A>T in PAH gene is an intronic change that involves a non-conserved nucleotide. 5/5 programs in Alamut predict that this variant does not affect a normal splicing pattern, however no functional studies supporting this notion were published at the time of evaluation. The variant is present in the control population dataset of ExAC at frequency of 0.008876 (1049/ 118182 chrs tested), predominantly in individuals of African descent (0.08901; 910/ 10224 chrs tested), including 33 homozygotes. The observed frequencies exceed the maximum expected allele frequency for a pathogenic variant of 0.0079 suggesting that it is a benign polymorphism. The variant of interest has been reported in PKU individuals without strong evidence for causality, but is cited as Benign by a reputable database/clinical laboratory. Taking together, based on the prevalence of this variant in general population the variant was classified as Benign. -

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -
PAH-specific ACMG/AMP criteria applied: BA1: Highest MAF=0.10514 in 1000G. 35 homozygotes in ExAC; BP4: HSF: No significant splicing motif alteration detected.
