Comment on list classification: Updated rating from Red to Amber following external review by Zornitza Stark. Not yet associated with a disorder in OMIM, and two cases in the current literature (PMID:27694521).

PMID:27694521: Edvardson et al. 2017 studied 2 unrelated families (two siblings from consanguineous Moslem-Arab parents, and a son of unrelated Sephardic-Jewish parents) who suffered from ID and seizures. PIGC variants were found: homozygous p.L189W in one family, and compound het variant (L212P/R21X) in another.
