The c.1141A>G (p.R381G) alteration is located in exon 11 (coding exon 9) of the GTF2H1 gene. This alteration results from a A to G substitution at nucleotide position 1141, causing the arginine (R) at amino acid position 381 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
