Collection Method: clinical testing

The c.403G>T (p.G135C) alteration is located in exon 5 (coding exon 4) of the UBAP2L gene. This alteration results from a G to T substitution at nucleotide position 403, causing the glycine (G) at amino acid position 135 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
