The c.875C>A (p.P292H) alteration is located in exon 7 (coding exon 7) of the NPIPB5 gene. This alteration results from a C to A substitution at nucleotide position 875, causing the proline (P) at amino acid position 292 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
