The c.833C>A (p.P278H) alteration is located in exon 7 (coding exon 7) of the CNBD2 gene. This alteration results from a C to A substitution at nucleotide position 833, causing the proline (P) at amino acid position 278 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
