The c.496C>A (p.P166T) alteration is located in exon 5 (coding exon 4) of the HMP19 gene. This alteration results from a C to A substitution at nucleotide position 496, causing the proline (P) at amino acid position 166 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
