Collection Method: clinical testing

The c.2496G>C (p.K832N) alteration is located in exon 7 (coding exon 6) of the SUGP2 gene. This alteration results from a G to C substitution at nucleotide position 2496, causing the lysine (K) at amino acid position 832 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
