Holoprosencephaly

Holoprosencephaly

Holoprosencephaly is a Central Nervous System Condition with a structural brain anomaly in which the brain fails to cleave.

Identifying babies born with birth defects and collecting information about them is a first step in preventing birth defects. Florida is among the many states with a birth defects tracking system. This data, as part of the national picture, helps us find out where and when birth defects occur and who they affect.

In 2017-21, the rate per 10,000 live births with Holoprosencephaly in Alachua County, could not be generated because there were too few cases compared to 0.9 statewide.

  • Chart will display if there are at least three years of data.
  • Multi-year counts are a sum of the selected years, not an average.
  • Quartiles are calculated when data is available for at least 51 counties and are only based on counties with data.
  • Results are suppressed when the estimated case count is between 0 and 4.
  • *Rate = Number of cases per 10,000 live births. Rates are calculated if there are 5 or more cases.
  • As suggested by the National Birth Defects Prevention Network’s Guidelines for Conducting Birth Defects Surveillance, for small numbers of cases (30 or fewer), the Poisson distribution was used to generate confidence intervals. When the case count was greater than thirty, confidence intervals are calculated using the normal approximation. Confidence intervals for 2008-2010 are 95%. All other years are 99%.
