Genes affected

LHFPL5 (HGNC:21253): (LHFPL tetraspan subfamily member 5) This gene is a member of the lipoma HMGIC fusion partner (LHFP) gene family, which is a subset of the superfamily of tetraspan transmembrane protein encoding genes. Mutations in this gene result in deafness in humans, and a mutation in a similar gene in mice results in deafness and vestibular dysfunction with severe degeneration of the organ of Corti. It is proposed to function in hair bundle morphogenesis. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 3 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP3

MetaRNN computational evidence supports a deleterious effect, 0.882

BS1

Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.000223 (326/1461892) while in subpopulation NFE AF= 0.000276 (307/1112010). AF 95% confidence interval is 0.00025. There are 0 homozygotes in gnomad4_exome. There are 143 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The c.59G>A (p.R20Q) alteration is located in exon 1 (coding exon 1) of the LHFPL5 gene. This alteration results from a G to A substitution at nucleotide position 59, causing the arginine (R) at amino acid position 20 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
