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 03, 2024The c.154G>A (p.V52I) alteration is located in exon 4 (coding exon 3) of the LYPLA2 gene. This alteration results from a G to A substitution at nucleotide position 154, causing the valine (V) at amino acid position 52 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
