Genes affected
KLHL24 (HGNC:25947): (kelch like family member 24) The protein encoded by this gene is a ubiquitin ligase substrate receptor and is regulated by autoubiquitination. Variations in the translation initiation codon of this gene have been found, which result in an N-terminally truncated but more stable protein due to loss of the autoubiquitination function. The more stable mutant protein causes an increased ubiquitin and degradation of keratin 14, which leads to skin fragility and the potentially life-threatening disease epidermolysis bullosa. The encoded protein is also involved in the regulation of kainate receptors. [provided by RefSeq, Mar 2017]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 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), KLHL24. . Gene score misZ 2.8837 (greater than the threshold 3.09). Trascript score misZ 3.1276 (greater than threshold 3.09). GenCC has associacion of gene with hypertrophic cardiomyopathy, cardiomyopathy, familial hypertrophic, 29, with polyglucosan bodies, epidermolysis bullosa simplex 6, generalized, with scarring and hair loss.
BP4
Computational evidence support a benign effect (MetaRNN=0.31607753).

KLHL24-related disorder Uncertain:1
Uncertain significance, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesMay 15, 2024The KLHL24 c.53A>G variant is predicted to result in the amino acid substitution p.Asp18Gly. To our knowledge, this variant has not been reported in the literature or in a large population database, indicating this variant is rare. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
