Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 22, 2023The c.787A>G (p.I263V) alteration is located in exon 2 (coding exon 2) of the RMDN2 gene. This alteration results from a A to G substitution at nucleotide position 787, causing the isoleucine (I) at amino acid position 263 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
