Variant summary

Our verdict is Likely pathogenic. The variant received 9 ACMG points: 9P and 0B. PM2PM5PP2PP3_Strong

The NM_001031710.3(KLHL7):​c.1258C>A​(p.Arg420Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,461,762 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 13/22 in silico tools predict a damaging outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R420H) has been classified as Uncertain significance.

ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 9 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PM5
Other missense variant is known to change same aminoacid residue: Variant chr7-23167916-C-T is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 226128.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
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, 0.983
