Intrafamilial clinical variability is observed in, If the genetic alteration identified in the proband cannot be detected in the leukocyte DNA of either parent, the recurrence risk to sibs is greater than that of the general population because of the possibility of parental germline mosaicism. They often arise in conjunction with other ocular defects such as coloboma and orbital cyst.
