Collection Method: clinical testing

The c.68G>A (p.R23Q) alteration is located in exon 2 (coding exon 2) of the FAM69B gene. This alteration results from a G to A substitution at nucleotide position 68, causing the arginine (R) at amino acid position 23 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
