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 Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the KLHL7 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 12 curated pathogenic missense variants (we use a threshold of 10). The gene has 1 curated benign missense variants. Gene score misZ: 3.907 (above the threshold of 3.09). Trascript score misZ: 5.0301 (above the threshold of 3.09). GenCC associations: The gene is linked to PERCHING syndrome, retinitis pigmentosa 42, cold-induced sweating syndrome, retinitis pigmentosa.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.818
