[CIS-PAGID] CVID Risk for children

[Conley, Mary Ellen]

I use the same figure as Bodo - 10% but I come at it from a slightly different perspective.  Like Bodo, I consider the percentage of patients with CVID who have affected family members.  But some of that 10% is not really CVID - it may be IgA deficiency or abnormal serum immunoglobulins that are detected because of family studies rather than repeated or unusual infections.  It may be autoimmune disease.  I also have a gut feeling, but no data, that with the sickest patients, the risk may be a little higher.

I tell my patients 10%.
Why?
A maximum of 10-20% of CVID patients are familial (10% in AD families, and suspected additional 10% with new mutations).
So assuming 20% of CVID patients have a Mendelian form of CVID, and most of them seem to be autosomal-dominant, I In AD traits the risk of any offspring is 50%.
therefore arrive at an overall risk of 10% for an offspring of newly diagnosed CVID patients.
