Collection Method: clinical testing

The c.211A>G (p.M71V) alteration is located in exon 1 (coding exon 1) of the UBL4B gene. This alteration results from a A to G substitution at nucleotide position 211, causing the methionine (M) at amino acid position 71 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
