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.152G>A (p.G51E) alteration is located in exon 4 (coding exon 1) of the LHFPL2 gene. This alteration results from a G to A substitution at nucleotide position 152, causing the glycine (G) at amino acid position 51 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
