Scientists reveal why Zika Virus causes Microcephaly
In a study published in the US journal Science, a team of scientists led by Cheng-Feng Qin reported that they have solved the mystery of why Zika Virus causes Microcephaly, a birth defect marked by small head size that can lead to severe developmental problems in babies.

As per scientists, one single genetic change, likely to be acquired in 2013, gave the mosquito-borne virus the ability to cause severe fetal microcephaly.

By comparing contemporary Zika virus strains from the 2015 and 2016 South American epidemics, scientists found one critical mutation that conferred the ability to cause microcephaly in mouse models of fetal infection. That one change was S139N.

S139N replaced a serine amino acid with an asparagine at the 139th position of a Zika protein called prM. S139N change coincided with initial reports of microcephaly. This change also made the virus more lethal to human neuron precursor cells.
