The c.339G>T (p.K113N) alteration is located in exon 2 (coding exon 2) of the ARMC12 gene. This alteration results from a G to T substitution at nucleotide position 339, causing the lysine (K) at amino acid position 113 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
