The c.340G>T (p.A114S) alteration is located in exon 6 (coding exon 4) of the FAM126B gene. This alteration results from a G to T substitution at nucleotide position 340, causing the alanine (A) at amino acid position 114 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
