Some babies may be born with a normal head size, but may have underlying brain abnormalities, experience slow head growth and
develop microcephaly after birth, she said.
Children born to mothers infected with Zika can
develop microcephaly, a severe disease characterized by abnormally small heads and severe neurologic disabilities.
Children without the CASK gene
develop microcephaly and intellectual disabilities.
A far higher number of babies in Colombia have
developed microcephaly related to Zika virus infections than previously reported.
Neither set of pups
developed microcephaly, which Diamond says could be because the researchers infected the mothers so early during pregnancy that not much brain development had yet occurred.

But health officials suspect it may be behind a surge in cases of
microcephaly, a condition which causes babies to
develop abnormally small brains and skulls — leading to permanent disability or death.
Using human fetal «mini-brains» grown in 3 - D cultures, scientists determined that a specific protein produced by the Zika virus changes the properties of neural stem cells in the
developing brain of an infected fetus, potentially causing
microcephaly in newborns (Ki - Jun Yoon, abstract 103.06, see attached summary).
Babies born with
microcephaly may not
develop normally, leaving them severely disabled.
An association between Zika infections during pregnancy and the birth of babies with
microcephaly (a birth defect in which an infant's brain does not

developing human brain and retina.
microcephaly A condition that leaves babies with abnormally small heads and partially
developed brains.
Organoids grown from the cells of a patient carrying the gene for severe
microcephaly, however, didn't grow as large because those brain regions didn't
develop properly.
The disease has been linked to an increase in miscarriages, deaths in newborns, and birth defects, especially a condition known as
microcephaly, in which the brain does not fully
develop and babies are born with abnormally small heads.
