Collection Method: clinical testing

The c.92C>T (p.T31I) alteration is located in exon 1 (coding exon 1) of the UBR3 gene. This alteration results from a C to T substitution at nucleotide position 92, causing the threonine (T) at amino acid position 31 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
