*6
Patients with opioid dependence and carrying the CYP2D6*6 allele in addition to another no function allele may have an increased response to methadone maintenance therapy (MMT) as compared to patients carrying a normal function allele in combination with a no function allele. However, conflicting evidence has been reported. This drug-variant pair has been assigned a 鈥渘o recommendation鈥?by CPIC, as it was determined to be not clinically actionable. Other genetic and clinical factors may also affect response to MMT.
106
*4
Patients with opioid dependence and carrying the CYP2D6*4 allele in addition to another no function allele may have an increased response to methadone maintenance therapy (MMT) as compared to patients carrying a normal function allele in combination with a no function allele. However, conflicting evidence has been reported. This drug-variant pair has been assigned a 鈥渘o recommendation鈥?by CPIC, as it was determined to be not clinically actionable. Other genetic and clinical factors may also affect response to MMT.
105
*3
Patients with opioid dependence and carrying the CYP2D6*3 allele in addition to another no function allele may have an increased response to methadone maintenance therapy (MMT) as compared to patients carrying a normal function allele in combination with a no function allele. However, conflicting evidence has been reported. This drug-variant pair has been assigned a 鈥渘o recommendation鈥?by CPIC, as it was determined to be not clinically actionable. Other genetic and clinical factors may also affect response to MMT.
104
*2xN
Patients with opioid dependence and carrying the CYP2D6*2xN allele in combination with a normal function allele may have a decreased response to methadone maintenance therapy (MMT) as compared to patients carrying two normal function alleles. However, conflicting evidence has been reported. This drug-variant pair has been assigned a 鈥渘o recommendation鈥?by CPIC, as it was determined to be not clinically actionable. Other genetic and clinical factors may also affect a patient's response to MMT.
103
*2
Patients with opioid dependence and carrying the CYP2D6*2 allele in addition to an increased function allele may have a decreased response to methadone maintenance therapy (MMT) as compared to patients carrying two normal function alleles. However, conflicting evidence has been reported. This drug-variant pair has been assigned a 鈥渘o recommendation鈥?by CPIC, as it was determined to be not clinically actionable. Other genetic and clinical factors may also affect response to MMT.
102
*1xN
Patients with opioid dependence and carrying the CYP2D6*1xN allele in combination with a normal function allele may have a decreased response to methadone maintenance therapy (MMT) as compared to patients carrying two no function alleles. However, conflicting evidence has been reported. This drug-variant pair has been assigned a 鈥渘o recommendation鈥?by CPIC, as it was determined to be not clinically actionable. Other genetic and clinical factors may also affect a patient's response to MMT.
101
*1
Patients with opioid dependence and carrying the CYP2D6*1 allele in addition to an increased function allele may have a decreased response to methadone maintenance therapy (MMT) as compared to patients carrying two normal function alleles or two no function alleles. However, conflicting evidence has been reported. This drug-variant pair has been assigned a 鈥渘o recommendation鈥?by CPIC, as it was determined to be not clinically actionable. Other genetic and clinical factors may also affect response to MMT.
