The c.460C>A (p.L154M) alteration is located in exon 4 (coding exon 4) of the YIPF4 gene. This alteration results from a C to A substitution at nucleotide position 460, causing the leucine (L) at amino acid position 154 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
