Collection Method: clinical testing

The c.257C>G (p.T86S) alteration is located in exon 3 (coding exon 3) of the CDHR3 gene. This alteration results from a C to G substitution at nucleotide position 257, causing the threonine (T) at amino acid position 86 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
