Panel Version: 2.12
Comment on list classification: There is sufficient evidence to promote this gene to Green at the next GMS panel update - two distinct homozygous variants identified in 5 individuals from 4 families who all had ichthyosis among other features. Supportive in vitro studies that demonstrate functional impairment.

Panel Version: 1.68
Four individuals from 3 different Moroccan families with the same homozygous variant (c.C559T) in the GTF2E2 gene have been identified, as well as an additional patient from Asian origin with a distinct homozygous variant (c.448G>C). Predominant phenotype was that of trichothiodystrophy; however, all 5 individuals also had ID/DD, microcephaly and ichthyosis - and therefore adding GTF2E2 to these relevant panel.
