Meckel syndromePseudomeningocele: A pseudomeningocele is an abnormal collection of cerebrospinal fluid (CSF) that communicates with the CSF space around the brain or spinal cord. In contrast to a meningocele, in which the fluid is surrounded and confined by dura mater, in a pseudomeningocele, the fluid has no surrounding membrane but is contained in a cavity within the soft tissues.Seaver Cassidy syndrome: Seaver Cassidy syndrome is a very rare disorder characterized certain facial, genital, and skeletal deformities as well as an unusual susceptibility to bleeding. Seaver Cassidy syndrome was first described in 1991 by Laurie Seaver and Suzanne Cassidy.RhinorrheaEthmoid sinus: The ethmoidal sinuses or ethmoidal air cells of the ethmoid bone are one of the four paired paranasal sinuses. They are a variable in both size and number of small cavities in the lateral mass of each of the ethmoid bones and cannot be palpated during an extraoral examination.Rostral neuropore: The rostral neuropore or anterior neuropore is a region corresponding to the opening of the embryonic neural tube in the anterior portion of the developing prosencephalon. The central nervous system develops from the neural tube, which initially starts as a plate of cells in the ectoderm and this is called the neural plate, the neural plate then undergoes folding and starts closing from the center of the developing fetus, this leads to two open ends, one situated cranially/rostrally and the other caudally.AnencephalyMalformative syndrome: A malformative syndrome (or malformation syndrome) is a recognizable pattern of congenital anomalies that are known or thought to be causally related (VIIth International Congress on Human Genetics).Epicanthic fold: Epicanthic fold (), epicanthal fold, epicanthus, or simply eye fold are names for a skin fold of the upper eyelid, covering the inner corner (medial canthus) of the eye. Other names for this trait include plica palpebronasalis and palpebronasal fold..TRPP: TRPP (Transient Receptor Potential Polycystic) is a family of transient receptor potential ion channels which when mutated can cause polycystic kidney disease.
