The c.1289T>C (p.V430A) alteration is located in exon 6 (coding exon 5) of the NXPE4 gene. This alteration results from a T to C substitution at nucleotide position 1289, causing the valine (V) at amino acid position 430 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
