Hi!
One can do clinical immunogenetics through 2 subspecialties: medical genetics and allergy/immunology.
Immunogenetics deals with finding (through sequencing) genes and pathways not yet identified (or identified already) that impact the functioning of the immune system.
Usually this involves cases where the patient has a “mystery” disease—aka no regular lab test to confirm diagnosis, and likely abnormal immune panels (immunoglobulins, percentages of T/B/NK cell populations, or abnormal lymphocyte proliferation studies, among others). This can be clinically accompanied by either hyperinflammation or immunodeficiency (or both, most commonly).
Immunogenetics is an amazing field of discovery. With whole exome sequencing becoming so cheap it has been a revolution in the realm of immunodeficiencies, with many insights showing for example that many “deficiencies” are actually problems of immune dysregulation, and absence of one part of the immune system leads to autoimmunity, or inflammatory diseases that present in the same patient.
I am biased (AI-bound), but it is truly one of the last areas in Medicine where you still play a bit of the role of Dr House, and where uptodate won’t be very helpful (though NOMID, ImmGen, and other similar projects will).
