The c.967C>A (p.L323M) alteration is located in exon 9 (coding exon 9) of the OGFOD3 gene. This alteration results from a C to A substitution at nucleotide position 967, causing the leucine (L) at amino acid position 323 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
