Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1129G>A (p.G377S) alteration is located in exon 8 (coding exon 7) of the TDRKH gene. This alteration results from a G to A substitution at nucleotide position 1129, causing the glycine (G) at amino acid position 377 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
