The c.7041G>T (p.K2347N) alteration is located in exon 8 (coding exon 8) of the FAM186A gene. This alteration results from a G to T substitution at nucleotide position 7041, causing the lysine (K) at amino acid position 2347 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
