Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2023The c.133T>C (p.W45R) alteration is located in exon 2 (coding exon 2) of the RRNAD1 gene. This alteration results from a T to C substitution at nucleotide position 133, causing the tryptophan (W) at amino acid position 45 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
