The degree of learning disability is not predictable by pathogenic variant type or presence or absence of eye involvement [Dennert et al 2017, Blackburn et al 2018, Errichiello et al 2018]. It has been called also the SOX 2 anophthalmia syndrome 3 due to the frequent mutations and/or deletions found in the SOX2 gene. Both cases with patient's quality of life are noted in developing country. The features of this condition are present from birth. 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.
