Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.212G>A (p.R71Q) alteration is located in exon 2 (coding exon 2) of the FAM198A gene. This alteration results from a G to A substitution at nucleotide position 212, causing the arginine (R) at amino acid position 71 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
