The c.2454C>A (p.F818L) alteration is located in exon 13 (coding exon 12) of the PPP1R13L gene. This alteration results from a C to A substitution at nucleotide position 2454, causing the phenylalanine (F) at amino acid position 818 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
