Collection Method:clinical testing

The c.632C>T (p.T211M) alteration is located in exon 6 (coding exon 6) of the UHRF1BP1 gene. This alteration results from a C to T substitution at nucleotide position 632, causing the threonine (T) at amino acid position 211 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
