not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2023The c.274C>A (p.L92M) alteration is located in exon 2 (coding exon 2) of the PPFIA4 gene. This alteration results from a C to A substitution at nucleotide position 274, causing the leucine (L) at amino acid position 92 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
