Ectrodactyly-ectodermal dysplasia- clefting syndrome (also k/a. split hand- split foot malformation /split hand-split foot ectodermal. Ectrodactyly–ectodermal dysplasia–cleft syndrome, or EEC, and also referred to as EEC syndrome is a rare form of ectodermal dysplasia, an autosomal. Disease definition. EEC syndrome is a genetic developmental disorder characterized by ectrodactyly, ectodermal dysplasia, and orofacial clefts (cleft lip/ palate).

Molecular genetic testing can confirm a diagnosis of EEC syndrome. Subsequently, Walker and Clodius described three pedigrees with complete unilateral or bilateral clefts of the primary and secondary syndroe associated with lobster-claw hands and feet and malfunction of the lacrimal system. The cleft lip was repaired with use of the Millard incision, and the palate was repaired using the Bardach two flap palatoplasty technique.

The most common syndromes within this group are hypohidrotic and hidrotic ectodermal dysplasias. Extraoral examination showed thin and sparse hair on the scalp that was lighter in color, frontal bossing, depressed nasal bridge, sparse eyelashes on the lower eyelids, dry and warm facial skin, and a surgical scar on the upper lip that was operated.

The present case could be a sporadic one as there was no previous history of the disorder in the family.

In clinically diagnosed EEC syndrome patients, mutation analysis of the TP63 gene is the first test to perform; if negative, testing for chromosomal abnormalities can be considered. The scalp, hair and eyebrows were light, dysp,asia-clefting, thin, brittle and kinky. EEC syndrome, argto-gln TP63 mutation and micturition difficulties: In conclusion, the ideal treatment plan includes early diagnosis and a multidisciplinary approach.

Invon Walter described the characteristic crab foot, which Cruveilhier later coined the “lobster foot”. Group B includes disorders involving one of the classical signs associated with another ectodermal sign. A variety of tests may be used to evaluate individuals with EEC syndrome.

TP63 mutation and clefting modifier genes in an EEC syndrome family. If hearing impairment is present, hearing aids may be beneficial. Molecular genetic testing can also be performed on these cells. Barakat syndrome Tricho—rhino—phalangeal syndrome. A year-old man syncrome to our unit with a chief complaint of cleft lip and cleft palate.

Imaging techniques may include traditional x-rays can be used assess abnormalities of the limbs and face.

The family history was non-contributory and gave no history of consanguineous marriage between parents.

Detailed information Professionals Summary information Greekpdf Clinical genetics review English Please review the contents of the section and add the appropriate syncrome if you can. They suggested that there is an association with isolated growth hormone deficiency, the latter being secondary to developmental hypothalamic defects. EEC syndrome is a rare autosomal dominant multiple congenital anomaly syndrome with variable expression.

Keywords Cleft lip and palate, ectodermal dysplasia, ectrodactyly.

Ectrodactyly-ectodermal dysplasia clefting syndrome (EEC syndrome)

Ectrodactyly of hands and feet showing lobster — claw like deformity. A normal human karyotype includes 22 pairs of ecrrodactyly-ectodermal or non-sex chromosomes and one pair of sex chromosomes, constituting a total of 46 chromosomes.

Some cases occur sporadically with no previous family history of the disorder i. In some cases, affected individuals may have genitourinary anomalies.

The right foot shows a deformity of the second metatarsal and absence of phalanges of the second digit [Figure 5]. There is considerable overlap among these disorders and some researchers consider them different expressions of one disease process.

Ectrodactyly–ectodermal dysplasia–cleft syndrome

Surgery may be indicated when pain or infection is present or when kidney function is compromised. A disorder formerly designated EEC syndrome type 2 no longer exists.

Please review dysplasia-lcefting privacy policy. Some individuals with EEC syndrome have developed hearing loss. They found the association in 4 other unpublished patients, indicating that anal atresia may constitute a true manifestation of this autosomal dominant syndrome with variable expression.


The ureteral malformations were thought to be of epithelial origin as was also the defect in the thymus. It is a rare syndrome, with the frequency of ectrodactyly at 1. Additional distinctive facial features can occur including an undeveloped upper jaw maxillary hypoplasiaa broad nasal tip, an abnormally long groove philtrum between the nose and the ectrodadtyly-ectodermal lip, and narrowing or blockage of the nasal airways choanal atresia.

Molecular basis of EEC ectrodactyly, ectodermal dysplasia, clefting syndrome: Synopsis of hand malformations with particular emphasis on genetic factors.

Conflicts of interest All authors have none to declare. EEC syndrome-1 Autosomal dominant 2. Pattern of p63 mutations and their phenotypes — update.

The patient was taken to the operating room for repair of the cleft lip and palate under general anesthesia. Symptoms can vary greatly from one person ectrodactyly-ectovermal another. Together we are strong. Articulation is further impaired by the numerous dental anomalies, including missing or malformed teeth found in EEC syndrome.

Orphanet: EEC syndrome

Her father had normal dark hair, dry skin, split right hand, bifid right thumb, and flexion contracture of the distal phalanx of the left index finger. Different combinations of ectodermal dysplasia, orofacial clefting and limb malformation are seen in five different syndromes: The facial and limb differences can be socially isolating and physically challenging for both children and adults.

Conclusion Early diagnosis would help parents to get accurate counseling. She had split hands and split right foot, as well as syndactyly of the right fourth and fifth toes. Clinical Synopsis Toggle Dropdown.
