Etymologically, the entry records: First described in 1978 by D. Pitt and I. Hopkins, in unrelated patients. Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is Pitt-Hopkins syndrome, spelled P-I-T-T---H-O-P-K-I-N-S- -S-Y-N-D-R-O-M-E, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
