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.486G>T (p.K162N) alteration is located in exon 5 (coding exon 2) of the LHFPL2 gene. This alteration results from a G to T substitution at nucleotide position 486, causing the lysine (K) at amino acid position 162 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
