Collection Method: clinical testing

The c.1016G>A (p.R339Q) alteration is located in exon 10 (coding exon 9) of the DUS1L gene. This alteration results from a G to A substitution at nucleotide position 1016, causing the arginine (R) at amino acid position 339 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
