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 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), KLHL7. . Gene score misZ 3.907 (greater than the threshold 3.09). Trascript score misZ 5.0301 (greater than threshold 3.09). GenCC has associacion of gene with PERCHING syndrome, retinitis pigmentosa 42, cold-induced sweating syndrome, retinitis pigmentosa.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.864
