Peter H. Byers is an American geneticist, physician, and researcher of connective tissue disorders.
[1] Byers graduated from Case Western Reserve University School of Medicine in 1974.
He then trained at the University of Washington School of Medicine as a fellow in medical genetics and biochemistry before joining the faculty in 1977.
[1] In addition to identifying specific genes and mutations underlying various connective tissue disorders, Byers' work established parental mosaicism as an underlying cause that genetically dominant disorders could be born to parents who were unaffected by such diseases.
[1][3] Byers helped to found the field of molecular genetic pathology, and has had leadership roles in multiple professional organizations relevant to that discipline.
