The c.280G>T (p.D94Y) alteration is located in exon 4 (coding exon 4) of the NKAIN3 gene. This alteration results from a G to T substitution at nucleotide position 280, causing the aspartic acid (D) at amino acid position 94 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
