Variant summary
Our verdict is Likely benign. Variant got -3 ACMG points: 2P and 5B. PM2BP4_StrongBP6
The ENST00000320301.11(PCDH15):āc.1256A>Gā(p.Asn419Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000886 in 1,614,074 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. N419H) has been classified as Uncertain significance.

Usher syndrome type 1 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Illumina Laboratory Services, Illumina | Jan 13, 2018 | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. - |
not specified Benign:1
Likely benign, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Sep 29, 2014 | p.Asn419Ser variant in exon 11 of PCDH15: This variant is not expected to have c linical significance because it has been identified in 0.136% (6/4406) of Afric an American chromosomes by the NHLBI Exome Sequencing Project, and in 1.639% (2/ 122) of African American chromosomes and in 0.568% (1/176) of Nigerian chromosom es by the 1000 Genomes Project (http://evs.gs.washington.edu/EVS/; dbSNP rs14382 7620). In addtion, asparaginine (Asn) at position 419 is not well conserved in m ammals or evolutionarily distant species with many fish carrying a serine (Ser) at this position and computational prediction tools do not suggest a high likeli hood of impact to the protein. which supports that variants at this position may be tolerated. - |
