Collection Method: clinical testing

The c.292G>A (p.D98N) alteration is located in exon 5 (coding exon 3) of the RMND5B gene. This alteration results from a G to A substitution at nucleotide position 292, causing the aspartic acid (D) at amino acid position 98 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
