The c.1101G>T (p.K367N) alteration is located in exon 11 (coding exon 10) of the AXDND1 gene. This alteration results from a G to T substitution at nucleotide position 1101, causing the lysine (K) at amino acid position 367 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
