Genes affected

LGALS13 (HGNC:15449): (galectin 13) Lysophospholipases are enzymes that act on biological membranes to regulate the multifunctional lysophospholipids. The protein encoded by this gene has lysophospholipase activity. It is composed of two identical subunits which are held together by disulfide bonds. This protein has structural similarity to several members of the beta-galactoside-binding S-type lectin family. [provided by RefSeq, Jul 2008]

The c.380C>T (p.S127L) alteration is located in exon 4 (coding exon 4) of the LGALS13 gene. This alteration results from a C to T substitution at nucleotide position 380, causing the serine (S) at amino acid position 127 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
