The c.1466C>A (p.P489H) alteration is located in exon 12 (coding exon 12) of the KDM7A gene. This alteration results from a C to A substitution at nucleotide position 1466, causing the proline (P) at amino acid position 489 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
