The c.49C>G (p.L17V) alteration is located in exon 2 (coding exon 2) of the CYB5R1 gene. This alteration results from a C to G substitution at nucleotide position 49, causing the leucine (L) at amino acid position 17 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
