The intelligence quotient (IQ) motif and SEC7 domain containing protein 2 gene (IQSEC2) is located on the X-chromosome and harbors mutations that contribute to non-syndromic ID with and without early-onset seizure phenotypes in both sexes.

We report these cases to demonstrate the exhaustive work-up prior to finding the changes in IQSEC2 gene, recommend that this gene be considered earlier in the diagnostic evaluation of individuals with global developmental delay, microcephaly, and severe, intractable epilepsy, and support the use of intellectual disability panels including IQSEC2 in the first-line evaluation of these patients.

However, depending on the severity of the mutation, the phenotypic spectrum of IQSEC2-related ID can range from the classic X-linked nonsyndromal form of the disease to a severe syndrome that has been reported in the context of de novo mutations only, in both male and female patients.

Taken together, the data suggest that gains in Xp11.22 including IQSEC2 cause ID and are associated with hyperactivity and attention-deficit/hyperactivity disorder, and are likely to be dosage-sensitive in males.

Overall, our data suggest that heterozygous loss-of-function of the escape genes KDM5C and/or IQSEC2 can contribute to severe ID in female patients and should be taken into account in diagnostics.

We propose that truncating mutations in IQSEC2 are responsible for syndromic severe ID in male patients and should be screened in patients without mutations in MECP2, FOXG1, CDKL5 and MEF2C.
