Genes affected

LHFPL3 (HGNC:6589): (LHFPL tetraspan subfamily member 3) 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 one LHFP-like gene result in deafness in humans and mice, and a second LHFP-like gene is fused to a high-mobility group gene in a translocation-associated lipoma. A partial gene fragment named LHFPL4 corresponds to a portion of the first exon of this gene. [provided by RefSeq, Jul 2008]

The c.157G>T (p.V53L) alteration is located in exon 1 (coding exon 1) of the LHFPL3 gene. This alteration results from a G to T substitution at nucleotide position 157, causing the valine (V) at amino acid position 53 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
