[3]:571 EEC is characterized by the triad of ectrodactyly, ectodermal dysplasia, and facial clefts. The family received genetic counseling, and a possible diagnosis of ectrodactyly-ectodermal dysplasia-clefting (EEC) syndrome was given to the family. Expression can be extremely variable, and the syndrome may occur as a new mutation. The ectodermal dysplasia in EEC is characterized by hypohidrosis, hypotrichosis, and anodontia. Ectrodactyly–ectodermal dysplasia–cleft syndrome, or EEC, and also referred to as EEC syndrome and split hand–split foot–ectodermal dysplasia–cleft syndrome: 520 is a rare form of ectodermal dysplasia, an autosomal dominant disorder inherited as a genetic trait. Light-colored hair and scalp and earlobe defects are observed. The occurrence of all three disorders in one, that is, ectrodactyly, ectodermal dysplasia , and cleft lip/palate, is reported to be approximately 1.5/100 million. The effect is a non-progressive defect in the development of two or more tissues derived from embryonic ectoderm. EEC syndrome is characterized by deformities of the hands and feet (ectrodactyly), abnormalities of the skin, hair, and nails (ectodermal dysplasia ), and cleft lip and/or cleft palate (clefting). Ectodermal dysplasia (ED) refers to a heterogeneous group of genetic disorders that cause abnormal ectoderm development. Delivery was at term with a birth weight of 3.33 kg (~40%), length of 48 cm (~10%) and head circumference of 33 cm (3%). (EEC stands for ectrodactyly, ectodermal dysplasia, and facial cleft.) The hereditary condition called split-hand/split-foot malformation and sometimes called lobster-claw deformity is also termed ectrodactyly, as does another hereditary disorder called the EEC syndrome. Ectodermal dysplasia, ectrodactyly, and clefting syndrome. A … Ectrodactyly–ectodermal dysplasia–cleft syndrome, or EEC, and also referred to as EEC syndrome [1] (also known as "Split hand–split foot–ectodermal dysplasia–cleft syndrome" [2]:520) is a rare form of ectodermal dysplasia, an autosomal dominant disorder inherited as an genetic trait. Ectrodactyly-ectodermal dysplasia clefting syndrome is a rare genetic disorder characterized by the triad of ectrodactyly-ectodermal dysplasia and facial clefting of lip or palate or both along with some systemic manifestations.

The ectrodactyly, ectodermal dysplasia, and clefting (EEC) syndrome is an autosomal dominant disorder characterized by a lobster-claw limb anomaly (ectrodactyly), which may be present in one or more limbs, cleft lip and palate, and ectodermal dysplasia. The limb anomalies include ectrodactyly (in 2/3 of patients), split-hand/split-foot, or polysyndactyly. : 571 EEC is characterized by the triad of ectrodactyly, ectodermal dysplasia, and facial clefts. There is ongoing research related to therapies for many of the ectodermal dysplasias. Ectrodactyly, ectodermal dysplasia, and cleft lip/palate syndrome-3 (ECC3) is an autosomal dominant disorder comprising absence of the central parts of the hands and feet, resulting in split-hand/foot malformation, ectodermal dysplasia, and cleft lip with or without cleft palate (summary by Maas et al., 1996).. Also see EEC1 (), which has been mapped to chromosome 7q11. Cleft lip and palate results in a characteristic nasal contour. Ectrodactyly observed in an individual with ectodermal dysplasia, ectrodactyly, and … Consultation with a medical geneticist is recommended for most current recommendations. Ectrodactyly-ectodermal dysplasia-clefting syndromeDefinitionEctrodactyly-ectodermal dysplasia-clefting (EEC) syndrome is one of more than 100 ectodermal dysplasia syndromes. Associated findings may include lacrimal-duct abnormalities, urinary tract anomalies, dysmorphic facies, and developmental delay. [ 6 ] EEC syndrome shows an autosomal dominant inheritance pattern with variable expressivity and incomplete penetrance, although autosomal recessive inheritance has also been reported.
