Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.38T>C (p.L13P) alteration is located in exon 2 (coding exon 1) of the GLYATL3 gene. This alteration results from a T to C substitution at nucleotide position 38, causing the leucine (L) at amino acid position 13 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
