The c.323G>A (p.S108N) alteration is located in exon 3 (coding exon 2) of the TCHP gene. This alteration results from a G to A substitution at nucleotide position 323, causing the serine (S) at amino acid position 108 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
