Collection Method: clinical testing

The c.347C>T (p.A116V) alteration is located in exon 5 (coding exon 4) of the GLYATL3 gene. This alteration results from a C to T substitution at nucleotide position 347, causing the alanine (A) at amino acid position 116 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
