A program on the topic of Jewish identity will be presented May 19 at Temple Israel.

The presentation by Harry Ostrer, a medical geneticist, will take place at 10 a.m. at the synagogue, 14 Coleytown Road. The event is open to the public free of charge.

Ostrer will discuss his recently published book, "Legacy: A Genetic History of the Jewish People." He will share "insights into the work of scientific pioneers and explain how his and their discoveries offer a fresh perspective on the genetics of the contemporary Jewish people," according to a press statement.

Ostrer, a medical doctor, is a professor of pathology, genetics and pediatrics at Albert Einstein College of Medicine and director of genetic and genomic testing at Montefiore Medical Center. He investigates the genetic basis of common and rare disorders and, in the diagnostic laboratory, translates the findings of genetic discoveries into tests that can be used to identify people's risks for having a disease prior to its occurrence, or for predicting its outcome once it has occurred, according to the release.

For more than 30 years, Ostrer has studied the genetic basis of single-gene disorders in Jewish populations and implemented new genetic tests and screening programs to benefit Jewish people. In 2007, he organized the Jewish HapMap Project, an international effort to map and sequence the genomes of Jewish people, according to the release.
