Abstract

Öz



Ağır kombine immün yetmezlik immün sistem hücrelerinin defektleri ile
ilgili olan nadir görülen genetik bir hastalıktır. Bu hastalık T lenfosit, B
lenfosit ve Doğal Öldürücü (NK) lenfosit gruplarının birinde veya birkaçında
görülebilir. Çalışmamızda Türkiye’nin güneyinde yer alan ağır kombine immün
yetmezlikli hastalarda IL7R gen polimorfizmlerinin
tanımlanması ve hastaların immünfenotip sonuçları ile birlikte değerlendirilmesi
amaçlandı. Çalışmamızda ağır kombine immün yetmezlik tanısı alan 30 hastanın
sanger DNA dizi analizi yöntemi ile analizi yapıldı. Hastalardan taze kan
örnekleri alınarak akım sitometri yöntemi ile hastalardaki IL7R gen
polimorfizmlerinin fenotiplendirilmesi yapıldı. Çalışmanın sonunda ağır kombine
immün yetmezlikli hastalardan birinde (%3,3; 1/30) heterozigot p.R140Q
(c.419G>A) mutasyonu tespit edilirken, hastaların 26’sında (%86,7; 26/30) de
heterozigot ve/veya homozigot IL7R
polimorfizmleri (T166I, I138V, T244I ve I356V) saptandı. Ağır immün yetmezlikli
hastalarda IL7R gen polimorfizmlerinin sık görülmesi, bu polimorfizm ile
hastalık arasında ilişki olduğu görüşünü güçlendirmiştir.

 

Abstract

Severe
combined immunodeficiencies are a group of rare inherited disorders with
profound defects in immune cells. This genetic disorder might have effect on T
lymphocytes, B
lymphocytes and/or Natural Killer cells (NK).
This study aimed at the
identifying the polymorphisms in IL7R
gene present in severe combined immunodeficies patients who located in southern
part of Turkey. A total of 30 patients with severe combined immunodeficiencies
were investigated for IL7R
polymorphisms using Sanger sequencing and immune phenotyping by flow cytometric
analysis. One heterozygote p.R140Q (c.419G>A) mutation was identified in 1
patient
(n=1, %3,3)
and
86.7% (n=26) of all patients had IL7R
polymorphisms (T166I, I138V, T244I and I356V) whether heterozygote and/or
homozygote. The frequent occurence of IL7R gene polymorphisms in patients with
severe immunodeficiency has strengthened the view that there is a relationship
between this polymorphism and disease.
