Ambry Genetics

Feb 27, 2023

The c.136G>C (p.D46H) alteration is located in exon 2 (coding exon 2) of the RRNAD1 gene. This alteration results from a G to C substitution at nucleotide position 136, causing the aspartic acid (D) at amino acid position 46 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
