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 was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.1832124).

BS1

Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.0000171 (25/1461754) while in subpopulation EAS AF = 0.000202 (8/39698). AF 95% confidence interval is 0.0000993. There are 0 homozygotes in GnomAdExome4. There are 12 alleles in the male GnomAdExome4 subpopulation. Median coverage is 34. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
