Collection Method: clinical testing

The c.2789T>G (p.F930C) alteration is located in exon 22 (coding exon 22) of the SCUBE2 gene. This alteration results from a T to G substitution at nucleotide position 2789, causing the phenylalanine (F) at amino acid position 930 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
