Variant summary
Our verdict is Benign. Variant got -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBA1
The NM_001384140.1(PCDH15):c.55T>G(p.Ser19Ala) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.229 in 1,610,862 control chromosomes in the GnomAD database, including 44,316 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S19T) has been classified as Likely benign.

Variant summary: The PCDH15 c.55T>G variant affects a non-conserved nucleotide, resulting in amino acid change from Ser to Ala. 3/4 in-silico tools predict benign outcome for this variant (SNPs&GO not captured due to low reliability index). This variant was found in 25808/118352 control chromosomes (3055 homozygotes) at a frequency of 0.2180614, which is about 69 times of the maximal expected frequency of a pathogenic PCDH15 allele (0.0031623), suggesting this variant is a benign polymorphism. This variant is reported in USH patients without evidence for causality and authors listed the variant as a frequent SNP. In addition, one reputable clinical laboratory via ClinVar classified this variant as benign. Taken together, this variant was classified as Benign. -

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 and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
