Multiple choice

What is the name of the gene that encodes the dopamine transporter protein?

  1. DRD1

  2. DRD2

  3. DAT1

  4. COMT
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The gene that encodes the dopamine transporter protein is DAT1 (dopamine transporter gene). Variations in DAT1 have been associated with differences in dopamine transport and reward sensitivity, and have been implicated in substance abuse and addiction.

Multiple choice

Which genetic variation in the DAT1 gene has been linked to an increased risk of cocaine addiction?

  1. DAT1 VNTR

  2. DAT1 3'UTR VNTR

  3. DAT1 10-repeat allele

  4. DAT1 9-repeat allele
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The DAT1 10-repeat allele has been associated with an increased risk of cocaine addiction, possibly due to its effect on dopamine transport and reward processing.

Multiple choice

Which genetic variation in the COMT1 gene has been linked to an increased risk of alcoholism?

  1. COMT Val158Met

  2. COMT Met158Val

  3. COMT rs4680

  4. COMT rs4818
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The COMT Val158Met polymorphism has been associated with an increased risk of alcoholism, possibly due to its effect on dopamine metabolism and reward processing.

Multiple choice

  1. OPRM1 A118G

  2. OPRM1 G118A

  3. OPRM1 rs1799971

  4. OPRM1 rs1800442
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The OPRM1 A118G polymorphism has been associated with an increased risk of heroin addiction, possibly due to its effect on opioid sensitivity and reward processing.

Multiple choice

  1. GABRA2

  2. GABRB2

  3. GABRG2

  4. GABRD2
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The gene that encodes the gamma-aminobutyric acid (GABA) receptor subunit alpha 2 is GABRA2 (gamma-aminobutyric acid receptor subunit alpha-2 gene). Variations in GABRA2 have been associated with differences in GABAergic neurotransmission and have been implicated in substance abuse and addiction.
