Haig Kazazian
American geneticist
Haig Hagop Kazazian Jr. (July 30, 1937 – January 19/20, 2022) was an American professor in the Department of Genetic Medicine at Johns Hopkins University School of Medicine in Baltimore, Maryland. Kazazian was an elected member of the National Academy of Sciences and the American Academy of Arts and Sciences.
Kazazian determined the molecular basis of single-gene genetic disorders such as hemoglobinopathies and hemophilia and introduced prenatal diagnosis for such disorders. His group was the first to identify a disease-causing mutation resulting from jumping genes in humans. After this discovery, he focused on basic research into LINE retrotransposition in humans and its implications for disease.

Why this record matters
The subject matters to the general reference register because the source frames it as american geneticist. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q57403123. VIAF identifies the subject as 261145019. The Library of Congress control number is n89111227. 3 of 5 selected statements include explicit references; 1 carry qualifiers and 1 use preferred rank. The first chronological checks are 1937, 2022, 1918 and 1923.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
