Genes affected
DRD4 (HGNC:3025): (dopamine receptor D4) This gene encodes the D4 subtype of the dopamine receptor. The D4 subtype is a G-protein coupled receptor which inhibits adenylyl cyclase. It is a target for drugs which treat schizophrenia and Parkinson disease. Mutations in this gene have been associated with various behavioral phenotypes, including autonomic nervous system dysfunction, attention deficit/hyperactivity disorder, and the personality trait of novelty seeking. This gene contains a polymorphic number (2-10 copies) of tandem 48 nt repeats; the sequence shown contains four repeats. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.77C>T (p.A26V) alteration is located in exon 1 (coding exon 1) of the DRD4 gene. This alteration results from a C to T substitution at nucleotide position 77, causing the alanine (A) at amino acid position 26 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
