Absent pituitary gland in two brothers with an oral-facial-digital syndrome resembling OFDS II and VI: a new type of OFDS?
The oral-facial-digital syndromes (OFDS) comprise a group of heterogeneous genetic disorders. Considerable clinical overlap exists within the nine described types [Toriello, Clin Dysmorph 2:95-105, 1993], and with other entities such as Pallister-Hall (PH) syndrome and hydrolethalus syndrome, leading to difficulties in the classification of OFDS. We report on two brothers with findings overlapping OFDS II, VI, and Pallister-Hall syndrome who had congenital absence of the pituitary gland. This may represent a new type of OFDS or, alternatively, an example of phenotypic variability within the OFDS. It also emphasizes that agenesis of the pituitary gland can occur in a variety of syndromes with midline defects.
