Collection Method: clinical testing

The c.698G>C (p.S233T) 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 698, causing the serine (S) at amino acid position 233 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
