Genes affected
LYPLA2 (HGNC:6738): (lysophospholipase 2) Lysophospholipases are enzymes that act on biological membranes to regulate the multifunctional lysophospholipids. There are alternatively spliced transcript variants described for this gene but the full length nature is not known yet. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 08, 2023The c.674A>C (p.E225A) alteration is located in exon 10 (coding exon 9) of the LYPLA2 gene. This alteration results from a A to C substitution at nucleotide position 674, causing the glutamic acid (E) at amino acid position 225 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
