Collection Method: clinical testing

The c.203G>A (p.R68H) alteration is located in exon 5 (coding exon 3) of the PLPPR2 gene. This alteration results from a G to A substitution at nucleotide position 203, causing the arginine (R) at amino acid position 68 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
