The c.2647C>A (p.H883N) alteration is located in exon 8 (coding exon 8) of the CD101 gene. This alteration results from a C to A substitution at nucleotide position 2647, causing the histidine (H) at amino acid position 883 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
