Feb 28, 2023

The c.107A>C (p.N36T) alteration is located in exon 3 (coding exon 3) of the DYNLRB2 gene. This alteration results from a A to C substitution at nucleotide position 107, causing the asparagine (N) at amino acid position 36 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
