Collection Method: clinical testing

The c.383T>C (p.M128T) alteration is located in exon 5 (coding exon 4) of the GLYATL2 gene. This alteration results from a T to C substitution at nucleotide position 383, causing the methionine (M) at amino acid position 128 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
