Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 20, 2023The c.806C>G (p.P269R) alteration is located in exon 2 (coding exon 2) of the RMDN2 gene. This alteration results from a C to G substitution at nucleotide position 806, causing the proline (P) at amino acid position 269 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
