Variant summary

Our verdict is Likely pathogenic. Variant got 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. 12/21 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. R420C) has been classified as Likely pathogenic.

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 Likely_pathogenic. Variant got 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 Lovd as [Likely_pathogenic].
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, 0.983
