Collection Method: clinical testing

The c.211G>T (p.G71W) alteration is located in exon 2 (coding exon 2) of the KIAA1217 gene. This alteration results from a G to T substitution at nucleotide position 211, causing the glycine (G) at amino acid position 71 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
