Hypertelorism, and Ectodermal dysplasia

Some ectodermal dysplasias are here classified as congenital disorders characterized by abnormal development in 2 or more ectodermal structures (hair, nails, teeth, and sweat glands) without other systemic findings. Ectodermal dysplasia-13 of the hair/tooth type is characterized by severe oligodontia accompanied by anomalies of hair and skin (Issa et al., 2016).

Oculotrichoanal syndrome is a form of rare, multiple congenital anomalies/dysmorphic syndrome characterized by a combination of various nose, eye, gastrointestinal and genitourinary abnormalities. Clinical presentation is variable and often includes bifid and broad nasal tip, aberrant anterior hairline, coloboma, cryptophthalmos or unilateral anophthalmia, anal anomalies, and omphalocele. Intelligence and global development is normal.

Hartsfield syndrome is a rare, genetic, developmental defect during embryogenesis malformation syndrome characterized by the association of variable degrees of holoprosencephaly and uni- or bilateral ectrodactyly of the hands and/or feet. Additional variable features, including facial dysmorphism (e.g. hypertelorism, short bulbous nose, long philtrum, dysplastic/low-set ears, cleft lip and palate, tented upper lip), other brain malformations (such as corpus callosum agenesis, absent septum pellucidum, absent olfactory bulbs/tracts, vermian hypoplasia), pituitary gland-related endocrine disorders (e.g. central diabetes insipidus, hypogonadotropic hypogonadism) and hypothalamic dysfunction, may be associated.

Ablepharon macrostomia syndrome is an extremely rare multiple congenital malformation syndrome characterized by the association of ablepharon, macrostomia, abnormal external ears, syndactyly of the hands and feet, skin findings (such as dry and coarse skin or redundant folds of skin), absent or sparse hair, genital malformations and developmental delay (in 2/3 of cases). Other reported manifestations include malar hypoplasia, absent or hypoplastic nipples, umbilical abnormalities and growth retardation. It is a mainly sporadic disorder, although a few familial cases having been reported, and it displays significant clinical overlap with Fraser syndrome (see this term).

Cranioectodermal dysplasia (CED), also known as Sensenbrenner syndrome, is a rare autosomal recessive heterogeneous ciliopathy that is primarily characterized by skeletal abnormalities, including craniosynostosis, narrow rib cage, short limbs, and brachydactyly, and ectodermal defects. Nephronophthisis leading to progressive renal failure, hepatic fibrosis, heart defects, and retinitis pigmentosa have also been described (summary by Arts et al., 2011).For a discussion of genetic heterogeneity of cranioectodermal dysplasia, see CED1 (OMIM ).
