The c.3131G>T (p.G1044V) alteration is located in exon 26 (coding exon 20) of the ST18 gene. This alteration results from a G to T substitution at nucleotide position 3131, causing the glycine (G) at amino acid position 1044 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
