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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2021The c.533C>T (p.A178V) alteration is located in exon 4 (coding exon 3) of the LHFPL1 gene. This alteration results from a C to T substitution at nucleotide position 533, causing the alanine (A) at amino acid position 178 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
