Collection Method:clinical testing

The c.52T>C (p.Y18H) alteration is located in exon 2 (coding exon 2) of the REEP3 gene. This alteration results from a T to C substitution at nucleotide position 52, causing the tyrosine (Y) at amino acid position 18 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
