Other features frequently associated with VWS include hypodontia in 10-81% of cases, narrow arched palate, congenital heart disease, heart murmur and cerebral abnormalities, syndactyly of the hands, polythelia, ankyloglossia, and adhesions between the upper and lower gum pads. [3]
Marfanoid habitus, a highly arched palate and several other features of LFS can be found with Marfan syndrome, a connective tissue disorder. [4] The finding of aortic root dilation in both disorders suggests that a mutation in an unspecified connective tissue regulating gene may contribute to the etiology of LFS. [1] [5] [8] [13]
A high-arched palate (also termed high-vaulted palate) is where the palate is unusually high and narrow. It is usually a congenital developmental feature that results from the failure of the palatal shelves to fuse correctly in development, the same phenomenon that leads to cleft palate . [ 1 ]
In addition to these facial abnormalities, individuals also have an underdeveloped maxilla and/or mandible with a highly arched and narrow palate which makes speech a very difficult skill to master. Teeth are usually very late to come in and will be undersized and spaced far apart.
People with Shprintzen-Goldberg syndrome can experience a range of symptoms that vary in severity. Due to craniosynostosis, people with SGS may have a long and narrow head, wide spaced protruding eyes that may slant downwards, a high and narrow palate, a high and prominent forehead, a small lower jaw, and low-set posteriorly-rotated ears.
Malpuech facial clefting syndrome, also called Malpuech syndrome or Gypsy type facial clefting syndrome, [1] is a rare congenital syndrome.It is characterized by facial clefting (any type of cleft in the bones and tissues of the face, including a cleft lip and palate), a caudal appendage (a "human tail"), [2] [3] growth deficiency, intellectual and developmental disability, and abnormalities ...
Maxillary hypoplasia is the most common secondary deformity that results from cleft lip and cleft palate. Because of the subjective nature of the diagnosis, the incidence of maxillary hypoplasia in people with cleft lip and palate varies between 15-50%. It is estimated that 25-50% of these patients require surgical intervention. [7]
Patients with Cohen syndrome very frequently exhibit abnormal eyelash and eyelid morphology, teeth abnormalities, lingual aplasia or hypoplasia, arachnodactyly, chorioretinal dystrophy, downslanted palpebral fissures, gingival overgrowth, global developmental delay, a high and narrow palate, maxillary hypoplasia, zygomatic bone hypoplasia, hypotonia, intellectual disability, long eyelashes ...
