The article, “Recent efforts to dissect the genetic basis of alcohol use and abuse,” has been accepted for publication in Biological Psychiatry. Dr. Sandra Sanchez-Roige and Dr. Abraham Palmer are co-authors along with Toni Clarke. The paper can be found here.

Bonnie Lin joined the Palmer lab in August 2019 as a data analyst. She was born and raised in San Diego. She graduated from Amherst college with a background in statistics and neuroscience. Bonnie loves the process of using data and research to address health questions and disparities. In her free time, she’s happy to enjoy San Diego’s nice weather at home and to study MBTI types (she’s an ENTJ). Additionally, she likes almost all things “green”- matcha, being vegetarian, cycling, reducing waste, etc.

Welcome, Bonnie!

A recent study, “Large-scale GWAS reveals insights into the genetic architecture of same-sex sexual behavior,” published in Science Magazine found that there is no single gene that leads to non-heterosexual behavior. The study was conducted by Dr. Andrea Ganna and colleagues.

KUSI News interviewed Dr. Abraham Palmer on what the study findings may mean. Dr. Palmer, who was not involved in the study, noted that researchers were able to identify “a few specific genes that influence non-heterosexual behavior in both men and women.” However, the study did not establish a way

Eden’s project focused on calling genotypes for the X and Y chromosomes using GBS data. She was able to adapt the pipeline for use in the sex chromosomes but discovered that imputation was much less successful because the reference genotype data that we had been using for the autosomes is much less complete for the sex chromosomes. Future work will use high and low coverage whole genome sequence data to discover and call SNPs on the sex chromosomes.

The article, “Genetic risk for major depressive disorder and loneliness in sex-specific associations with coronary artery disease,” was accepted for publication in Molecular Psychiatry.

The goal of the center is to use outbred rats to study the genetic basis of drug self-administration and related behavioral traits. More information is available at www.ratgenes.org.

Drs. Amanda Barkley-Levenson and Dr. Abraham Palmer attended the Research Society on Alcoholism conference in Minneapolis, Minnesota on June 22-26.

Amanda presented a poster titled, “Glyoxalase 1 and sensitivity to the motivational effects of ethanol.”

Abraham presented a talk titled, “Dissecting the genetics of alcohol Consumption and alcohol misuse, and overlap with alcohol dependence.” He also was a discussant for a symposium titled, “Using outbred N/NIH HS rats to perform GWAS for substance abuse-relevant traits.”
