Collection Method: clinical testing

The c.301C>A (p.R101S) alteration is located in exon 2 (coding exon 2) of the UBR2 gene. This alteration results from a C to A substitution at nucleotide position 301, causing the arginine (R) at amino acid position 101 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
