Genes affected

KLHL7 (HGNC:15646): (kelch like family member 7) This gene encodes a BTB-Kelch-related protein. The encoded protein may be involved in protein degradation. Mutations in this gene have been associated with retinitis pigmentosa 42. [provided by RefSeq, Feb 2010]

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 7-23167947-GC-G is Pathogenic according to our data. Variant chr7-23167947-GC-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 487515.Status of the report is criteria_provided_single_submitter, 1 stars.
