Variant summary

Our verdict is Uncertain significance. The variant received 5 ACMG points: 5P and 0B. PM2 PP2 PP3_Moderate

The NM_001031710.3(KLHL7):​c.352C>A​(p.Leu118Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. L118L) has been classified as Benign.

ACMG classification

Our verdict: Uncertain_significance. The variant received 5 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 retinitis pigmentosa 42, PERCHING syndrome, retinitis pigmentosa, cold-induced sweating syndrome.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.864
