GLI3-related Pallister-Hall syndrome (GLI3-PHS) is characterized by a spectrum of anomalies ranging from polydactyly, asymptomatic bifid epiglottis, and hypothalamic hamartoma at the mild end to laryngotracheal cleft with neonatal lethality at the severe end. Individuals with mild GLI3-PHS may be incorrectly diagnosed as having isolated postaxial polydactyly type A. Individuals with GLI3-PHS can have pituitary insufficiency and may die as neonates from undiagnosed and untreated adrenal insufficiency. [from GeneReviews]

Bamforth-Lazarus syndrome (BAMLAZ) is a rare autosomal recessive disorder characterized by congenital hypothyroidism due to thyroid agenesis or thyroid hypoplasia, cleft palate, and spiky hair, with or without choanal atresia or bifid epiglottis (summary by Sarma et al., 2022). [from OMIM]

A midline anterior-posterior cleft of the epiglottis that involves at least two-thirds of the epiglottic leaf. It is a useful feature for clinical diagnosis because it appears to be very rare in syndromes other than Pallister-Hall-Syndrome and is also rare as an isolated malformation. [from HPO]
