C.Ataxia Teleangiectasia
the reason its not DiGeorge Syndrome because her serum calcium levels are not in the hypocalcemic range.

yep, it's C.
we mustn't blindly fall for the absent thymic shadow trick anymore. they throw it in for a reason. [of course, don't ignore it if it's really DiGeorge! but use the other symptoms to arrive at the answer]

Thymic shadow triggers a response which leads to DiGeorge normally but the hypoplastic ovaries and her serum calcium should have been the landmines or the alarms which should go off in your head while reading the question. And believe me when i say this that Serum Calcium was the biggest sign, signal or warning in this question and if your lucky will find questions in the real exam in which the warning is so subtle that you dont even know it. So Read and Think very carefully so that in the exam it doesnt slow you down.

you guys are good...
The correct answer is C
This patient has thymic hypoplasia, depressed IgA, recurrent respiratory infections, hypoplastic ovaries and a normal serum calcium level. This fidings are consistent with ataxia teleangiectasia in an infant.
The normal calcium level differentieates this condition from Di George sy.
In AT: by age 2-3, cerebellar Purkinje cell degeneration causes ataxia. By age 4-6, the characteristic teleangiectasias appear on the face.
