Collection Method: clinical testing

The c.1310C>T (p.T437M) alteration is located in exon 11 (coding exon 9) of the CPSF2 gene. This alteration results from a C to T substitution at nucleotide position 1310, causing the threonine (T) at amino acid position 437 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
