The c.2464C>T (p.R822W) alteration is located in exon 15 (coding exon 12) of the NCOA7 gene. This alteration results from a C to T substitution at nucleotide position 2464, causing the arginine (R) at amino acid position 822 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
