Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.425T>C (p.M142T) alteration is located in exon 4 (coding exon 4) of the PLA2G16 gene. This alteration results from a T to C substitution at nucleotide position 425, causing the methionine (M) at amino acid position 142 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
