Collection Method:clinical testing

The c.460C>T (p.R154C) alteration is located in exon 3 (coding exon 3) of the IZUMO1R gene. This alteration results from a C to T substitution at nucleotide position 460, causing the arginine (R) at amino acid position 154 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
