The c.724C>G (p.L242V) alteration is located in exon 3 (coding exon 3) of the NR2F6 gene. This alteration results from a C to G substitution at nucleotide position 724, causing the leucine (L) at amino acid position 242 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
