Collection Method:clinical testing

The c.473C>A (p.A158D) alteration is located in exon 4 (coding exon 4) of the CDHR3 gene. This alteration results from a C to A substitution at nucleotide position 473, causing the alanine (A) at amino acid position 158 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
