The c.680G>A (p.G227E) alteration is located in exon 8 (coding exon 6) of the STK40 gene. This alteration results from a G to A substitution at nucleotide position 680, causing the glycine (G) at amino acid position 227 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
