Comment on list classification: Although brain anomalies are associated with this gene, neither of the two families reported to date affected by this condition had a history of seizures. Furthermore mosaicism was also not reported. Therefore recommending a Red gene rating at this time.

Comment on publications: PMID: 23687350 reports 2 sibs, born of consanguineous parents, with ID and megalencephaly had a homozygous 1-bp deletion (538delT) in the TBC1D7 gene, resulting in a frameshift and premature termination (Tyr180ThrfsTer1). A further report (PMID: 24515783) describes two sisters born to Italian parents from distant villages, homozygous for a 4-bp deletion (c.17_20delAGAG) in the TBC1D7 gene, resulting in a frameshift and premature termination (Arg7ThrfsTer21). Both children presented a similar phenotype consisting of mild ID, macrocrania, patellar dislocation as well as celiac disease.
