Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 15, 2024The c.3112A>G (p.M1038V) alteration is located in exon 18 (coding exon 16) of the RIMBP2 gene. This alteration results from a A to G substitution at nucleotide position 3112, causing the methionine (M) at amino acid position 1038 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
