Thank you for your query.
Absence of the septum pellucidum is reported to be an unusual anomaly that occurs in an estimated 2 to 3 individuals per 1 00,000 people in the general population .
When observed, this anomaly should serve as a due to the presence of associated anomalies, including holoprosencephaly
, septooptic dysplasia
, ab- normalities of the corpus callosum
, and Chiari II malformation .
There isn't much relation to fetal alcohol syndrome
There maybe chances of mental retardation and visua; problems in this baby.
