Collection Method: clinical testing

The c.655G>A (p.E219K) alteration is located in exon 6 (coding exon 6) of the RABEP1 gene. This alteration results from a G to A substitution at nucleotide position 655, causing the glutamic acid (E) at amino acid position 219 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
