Doctors remain perplexed by the condition, though they believe it may have something to do with genetics, as the boys’ mother and father are first cousins. “Our doctors are doing medical tests to determine why these kids remain active in the day but cannot open their eyes, why they cannot talk or eat when [the] sun goes down.” According to Akram, Shoaib and Abdual lost two brothers to the same condition, though their sister is unaffected.
So far, doctors have ruled out the unsubstantial theory that the boys receive energy from the sun, as they were able to move around during the day in a dark, enclosed room.
A 2012 study, for example, listed unplanned pregnancies, poor maternal nutrition, and higher rates of marriages between two related people as factors in the increased rate of birth defects in India. Consanguineous marriages, or unions between two relatives, appear to be one of the greatest risk factors for birth defects. According to a 2013 study, related married couples accounted for a third of babies born with abnormalities in Bradford, England.
Doctors hope that, with time, they’ll be able to learn what’s causing the disease, and prevent it from progressing with treatment.
