Genes affected

LHFPL2 (HGNC:6588): (LHFPL tetraspan subfamily member 2) 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. Alternatively spliced transcript variants have been found, but their biological validity has not been determined. [provided by RefSeq, Jul 2008]

The c.121C>T (p.R41C) alteration is located in exon 4 (coding exon 1) of the LHFPL2 gene. This alteration results from a C to T substitution at nucleotide position 121, causing the arginine (R) at amino acid position 41 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
