Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1034C>G (p.S345C) alteration is located in exon 4 (coding exon 3) of the TATDN2 gene. This alteration results from a C to G substitution at nucleotide position 1034, causing the serine (S) at amino acid position 345 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
