Collection Method: clinical testing

The c.2629G>A (p.E877K) alteration is located in exon 7 (coding exon 6) of the SUGP2 gene. This alteration results from a G to A substitution at nucleotide position 2629, causing the glutamic acid (E) at amino acid position 877 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
