Collection Method:clinical testing

The c.4456G>A (p.D1486N) alteration is located in exon 36 (coding exon 36) of the KCP gene. This alteration results from a G to A substitution at nucleotide position 4456, causing the aspartic acid (D) at amino acid position 1486 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
