To check which type of Thalassemia ?

Dear Friends,
I will share my Baby Mutational Analysis report to check whether it is major or intermedia thalassemia .
Also tell me which type of thalassemia i.e Alpha or Beta thalassemia

Interpretation:
Compound heterozygous for HBB:c.-138C>T and HBB:c.92 G>C mutations in the
p-globin gene.

Note:- Baby need regular Blood Transfusion from last 8 month ago.Now his age is 15 month.

Dear Andy,
kindly help to tell which type of thalassemia .

There are two types of beta thalassemia mutations: those that completely stop beta-globin production and those that only reduce beta-globin production. Mutations that render the HBB gene completely useless for beta-globin protein production are called "beta-zero" thalassemia mutations, and mutations that reduce the amount of beta-globin protein made from the HBB gene are known as "beta-plus" thalassemia mutations. Some beta-plus thalassemia mutations are relatively mild and only slightly reduce beta-globin production.

Gurpreet,
HBB:c.-138C>T is a beta-plus mutation  and
HBB:c.92 G>C  is a beta-zero mutation

As Jay as pointed out, the first mutation is a beta+ mutation that on its own is a mild mutation. However, the second mutation is a beta zero mutation. The combination of the two is a beta thal major phenotype, requiring transfusions.
If an alpha thal deletion had been present, it is likely that transfusion would have started at a later date, so I doubt any alpha deletion is present. By themselves, neither mutation is severe, but together, not much hemoglobin can be produced on its own. I would not be surprised if neither parent has had much issue with thal minor.
