Variant summary

Our verdict is Likely benign. Variant got -6 ACMG points: 2P and 8B. PM2 BP6_Very_Strong

The ENST00000395445.6(PCDH15):​c.4832_4833delinsCC​(p.Glu1611Ala) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Benign (★★). Another nucleotide change resulting in same amino acid change has been previously reported as Benignin ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E1611D) has been classified as Likely benign.

Genes affected

PCDH15 (HGNC:14674): (protocadherin related 15) This gene is a member of the cadherin superfamily. Family members encode integral membrane proteins that mediate calcium-dependent cell-cell adhesion. It plays an essential role in maintenance of normal retinal and cochlear function. Mutations in this gene result in hearing loss and Usher Syndrome Type IF (USH1F). Extensive alternative splicing resulting in multiple isoforms has been observed in the mouse ortholog. Similar alternatively spliced transcripts are inferred to occur in human, and additional variants are likely to occur. [provided by RefSeq, Dec 2008]

ACMG classification

Verdict is Likely_benign. Variant got -6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP6: Variant 10-53809211-CT-GG is Benign according to our data. Variant chr10-53809211-CT-GG is described in ClinVar as [Benign]. Clinvar id is 505045.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
