The c.463G>A (p.D155N) alteration is located in exon 6 (coding exon 4) of the STK40 gene. This alteration results from a G to A substitution at nucleotide position 463, causing the aspartic acid (D) at amino acid position 155 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
