Collection Method: clinical testing

The c.1169C>G (p.P390R) alteration is located in exon 9 (coding exon 8) of the GGNBP2 gene. This alteration results from a C to G substitution at nucleotide position 1169, causing the proline (P) at amino acid position 390 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
