Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2021The c.269G>A (p.R90H) alteration is located in exon 2 (coding exon 2) of the RTP2 gene. This alteration results from a G to A substitution at nucleotide position 269, causing the arginine (R) at amino acid position 90 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
