Dec 07, 2021

The c.243T>A (p.N81K) alteration is located in exon 3 (coding exon 3) of the MSRB2 gene. This alteration results from a T to A substitution at nucleotide position 243, causing the asparagine (N) at amino acid position 81 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
