[9] [10] Genetic causes are linked with most craniofacial syndromes, and CL/P and other orofacial clefts are recognized as heterogeneous disorders, meaning there are multiple recognized causes. [9] [11] Orofacial clefts have great phenotypic diversity, and their associated genetic environments have called for vast research and investigation.
Orofacial clefts may be associated with a syndrome (syndromic) or may not be associated with a syndrome (nonsyndromic). Syndromic clefts are part of syndromes that are caused by a variety of factors such as environment and genetics or an unknown cause. Nonsyndromic clefts, which are not as common as syndromic clefts, also have a genetic cause. [31]
VWS is the most common orofacial clefting syndrome, accounting for 2% of CLP cases. [3] The majority of VWS cases are caused by haploinsufficiency due to mutations in the interferon regulatory factor 6 gene (IRF6) on chromosome 1 in the 1q32-q41 region known as VWS locus 1. A second, less common, causative locus is found at 1p34, known as VWS ...
Language deficits are also associated with EEC syndrome and are attributed to two factors. Conductive hearing loss due to ossicular anomalies is often encountered in patients with EEC syndrome, which can have significant impacts on language acquisition. Also, the impaired cognitive functioning that sometimes accompanies EEC can inhibit language ...
Without treatment, Crouzon syndrome can cause hearing and vision loss, exposure keratitis or conjunctivitis, drying of the cornea, hydrocephalus, sleep apnea, and breathing problems. [medical citation needed] To move the orbits forward, surgeons expose the skull and orbits and reshape the bone. To treat the midface deficiency, surgeons can move ...
Axenfeld–Rieger syndrome is a rare autosomal dominant [2] disorder, which affects the development of the teeth, eyes, and abdominal region. [3]Axenfeld–Rieger syndrome is part of the so-called iridocorneal or anterior segment dysgenesis syndromes, [4] which were formerly known as anterior segment cleavage syndromes, anterior chamber segmentation syndromes or mesodermal dysgenesis.
Orofaciodigital syndrome type 1 is caused by mutations in the OFD1 gene. OFD1 localizes to both centrosomes and basal bodies within the human genetic cellular structure. This suggests that this syndrome may fall into a broad category of ciliary diseases. The ciliary organelles are present in many cellular types throughout the human body. Cilia ...
Ethmocephaly is a type of cephalic disorder caused by holoprosencephaly.Ethmocephaly is the rarest phenotypic variant of a group of defects called the holoprosencephaly (HPE) malformation sequence; other variants include cebocephaly, cyclopia, and median cleft palate. [1]
