Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2021The c.3066A>C (p.E1022D) alteration is located in exon 18 (coding exon 16) of the RIMBP2 gene. This alteration results from a A to C substitution at nucleotide position 3066, causing the glutamic acid (E) at amino acid position 1022 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
