Collection Method: clinical testing

The c.1027T>C (p.C343R) alteration is located in exon 10 (coding exon 7) of the GPBP1L1 gene. This alteration results from a T to C substitution at nucleotide position 1027, causing the cysteine (C) at amino acid position 343 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
