Turkish scientists say they have discovered a new immune deficiency disease and are calling for more research to stop what could be a serious problem.

Dr. Ismail Reisli of Selcuk University's Meram School of Medicine's Children Immunology and Allergy Department announced the disease Wednesday.

He has been studying a 13-year-old girl from Konya, Turkey, for the past three years, the Anadolu News Agency reports.

Reisli said the disease, CD19 Deficiency, is caused by a deficient immune system.

He warned it leaves a body susceptible to other illnesses like pneumonia, bronchitis and meningitis.

Reisli said people could die from it as well.
