Collection Method: clinical testing

The c.632C>T (p.A211V) alteration is located in exon 9 (coding exon 9) of the FAM122B gene. This alteration results from a C to T substitution at nucleotide position 632, causing the alanine (A) at amino acid position 211 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
