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

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 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.

BP4

Computational evidence support a benign effect (MetaRNN=0.21451503).

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬† is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 1992532). This variant has not been reported in the literature in individuals affected with KLHL7-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 33 of the KLHL7 protein (p.Val33Ile). -
