Collection Method: clinical testing

The c.589G>C (p.V197L) alteration is located in exon 8 (coding exon 5) of the GPBP1L1 gene. This alteration results from a G to C substitution at nucleotide position 589, causing the valine (V) at amino acid position 197 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
