Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 12, 2021The c.808C>T (p.R270W) alteration is located in exon 8 (coding exon 6) of the RMND5B gene. This alteration results from a C to T substitution at nucleotide position 808, causing the arginine (R) at amino acid position 270 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
