The c.872C>T (p.S291L) alteration is located in exon 8 (coding exon 6) of the CYB5RL gene. This alteration results from a C to T substitution at nucleotide position 872, causing the serine (S) at amino acid position 291 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
