Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2024The c.809G>A (p.R270Q) alteration is located in exon 8 (coding exon 6) of the RMND5B gene. This alteration results from a G to A substitution at nucleotide position 809, causing the arginine (R) at amino acid position 270 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
