ABSTRACT
BACKGROUND:
Severe Combined Immunodeficiency (SCID) is an autosomal recessive inborn error of immunity (IEI) characterized by recurrent chest and gastrointestinal (GI) infections and in some cases associated with life-threatening disorders. METHODOLOGY ANDRESULTS:
This current study aims to unwind the molecular etiology of SCID and also extended the patients' phenotype associated with identified particular variants. Herein, we present 06 disease-causing variants identified in 07 SCID-patients in three different SCID related genes. Whole Exome Sequencing (WES) followed by Sanger Sequencing was employed to explore genetic variations. The results included identification of two previously reported heterozygous variants in homozygous form for the first time in RAG1gene [(p.Arg410Gln);(p.Arg737His)], followed by a recurrent variant (p.Trp959*) in RAG1, a novel variant in IL2RG (p.Asp48Lfs*24), a recurrent variant in IL2RG (p.Gly271Glu) and a recurrent variant in DCLRE1C (p.Arg191*) gene.CONCLUSION:
To conclude, the immune-profiling and WES revealed two novel, two as homozygous state for the first time, and two recurrent disease causing variants contributing valuably to our existing knowledge of SCID.Palavras-chave
