2003 OCT 2 - (NewsRx.com & NewsRx.net) -- A D2S2944 allele is associated with an increased risk of depression and substance abuse in women.
"Major depressive disorder (MDD) and substance use disorders (SUD) are complex behavioral disorders with 40%5-50% heritability," scientists in the United States noted. "Recently, Zubenko and colleagues reported that the 124 bp allele of D2S2944, a tetranucleotide repeat marker on 2q35, is strongly associated with recurrent, early onset MDD (RE-MDD) and alcohol use disorders in women."
"To test this hypothesis," R. Philibert and colleagues at the University of Iowa "examined the association of the 124 bp allele in a subset of 171 adoptees from the Iowa Adoption Studies, a population with high rates of MDD and SUD."
In the study cohort, "the 124 bp allele significantly associated with RE-MDD in women," they found. "There was slight evidence of an increased of SUD in women with the 124 bp allele with the rate of cannabis use disorders reaching statistical significance (p
"Given the history of prior studies implicating 2q35 as a locus encoding vulnerability to co-morbid alcoholism and ...
