ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 17 ACMG points.

PM1
In a hotspot region, there are 5 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 4 uncertain in NM_001031710.3
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, 0.945
PP5
Variant 7-23140775-G-A is Pathogenic according to our data. Variant chr7-23140775-G-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 1008.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
