Genes affected

LHFPL1 (HGNC:6587): (LHFPL tetraspan subfamily member 1) 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]

Ambry Genetics

Oct 12, 2024

The c.434C>T (p.P145L) alteration is located in exon 3 (coding exon 2) of the LHFPL1 gene. This alteration results from a C to T substitution at nucleotide position 434, causing the proline (P) at amino acid position 145 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
