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.351G>A (p.M117I) alteration is located in exon 1 (coding exon 1) of the LHFPL3 gene. This alteration results from a G to A substitution at nucleotide position 351, causing the methionine (M) at amino acid position 117 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
