The c.617G>A (p.S206N) alteration is located in exon 3 (coding exon 3) of the THUMPD1 gene. This alteration results from a G to A substitution at nucleotide position 617, causing the serine (S) at amino acid position 206 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
