Collection Method: clinical testing

The c.931G>T (p.G311W) alteration is located in exon 1 (coding exon 1) of the AMER2 gene. This alteration results from a G to T substitution at nucleotide position 931, causing the glycine (G) at amino acid position 311 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
