Once again, the remaining exposure was derived from non-mutual environment event
The main one genome-wide linkage investigation regarding Sad accused a location to the chromosome 16 close to the gene encoding the brand new norepinephrine transporter. Almost every other genes from the Unfortunate were (1) a working variant during the ADRB1, the fresh new gene security brand new ?1-adrenergic receptor, and (2) one or two SNPs and you will a good step three-SNP haplotype on gene getting COMT within the women patients just who features Unfortunate (assessed when you look at the 107 ).
