CYP2B6*35 (c.-82T>C; c.329G>T, p.G110V; c.341T>C, p.I114T; c.444G>T, p.E148D; c.593T>C, p.M198T; c.835G>C, p.A279P) – Uncertain function: CYB2B6*35 is assigned uncertain function. Two in vitro studies using cDNA expression systems provided inconclusive evidence for CYP2B6*35 function (23418033, 30201214). Therefore, consensus among experts was uncertain function based on inadequate evidence.
