Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 22, 2023The c.238C>A (p.R80S) alteration is located in exon 2 (coding exon 2) of the RTP2 gene. This alteration results from a C to A substitution at nucleotide position 238, causing the arginine (R) at amino acid position 80 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
