The c.1939A>G (p.T647A) alteration is located in exon 16 (coding exon 10) of the ST18 gene. This alteration results from a A to G substitution at nucleotide position 1939, causing the threonine (T) at amino acid position 647 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
