The c.40C>G (p.P14A) alteration is located in exon 1 (coding exon 1) of the XKR7 gene. This alteration results from a C to G substitution at nucleotide position 40, causing the proline (P) at amino acid position 14 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
