Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 15, 2023The c.449A>G (p.D150G) alteration is located in exon 4 (coding exon 4) of the RRNAD1 gene. This alteration results from a A to G substitution at nucleotide position 449, causing the aspartic acid (D) at amino acid position 150 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
