Collection Method: clinical testing

The c.16A>G (p.S6G) alteration is located in exon 1 (coding exon 1) of the CLDND2 gene. This alteration results from a A to G substitution at nucleotide position 16, causing the serine (S) at amino acid position 6 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
