The c.869C>G (p.S290C) alteration is located in exon 6 (coding exon 5) of the NIF3L1 gene. This alteration results from a C to G substitution at nucleotide position 869, causing the serine (S) at amino acid position 290 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
