The c.986C>A (p.P329H) alteration is located in exon 2 (coding exon 2) of the KLHL42 gene. This alteration results from a C to A substitution at nucleotide position 986, causing the proline (P) at amino acid position 329 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
