Collection Method: clinical testing

The c.473G>C (p.R158T) alteration is located in exon 4 (coding exon 4) of the RABEP1 gene. This alteration results from a G to C substitution at nucleotide position 473, causing the arginine (R) at amino acid position 158 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
