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).

The ophthalmological examination revealed no abnormality and no epiphora. Although there is no specific cure for EEC syndrome, there are many treatments available for the various symptoms. The cosmetic aspects of EEC can have a tremendous impact on quality of life. Received Jun 5; Accepted Aug 5. During reproductioneach parent contributes 23 chromosomes; 22 autosomal chromosomes and one sex chromosome.

Some individuals may develop glandular abnormalities such as an underdeveloped thymus and reduced activity of the pituitary gland hypopituitarism. Heterozygous germline mutations in the p53 homolog p63 are the cause of EEC syndrome. The family history was non-contributory and gave no history of consanguineous marriage between parents. Knudtzon and Aarskog described 2 unrelated children with the EEC syndrome who also had growth hormone deficiency and isolated absent septum pellucidum.

Affected individuals or their parents should talk to their physician and medical team about their specific case, associated symptoms and overall prognosis.

Testing is available only on a clinical basis. Affected individuals often have abnormalities affecting the limbs including ectrodactyly, a condition in which part or all of the central digits fingers or toes are missing. Some individuals with isolated nonsyndrommic cleft lip also have mutations of the TP63 gene. Clinical description The three cardinal signs of the syndrome are ectrodactyly and syndactyly of the hands and feet, cleft lip with or without cleft palate that can result in speech defectsand abnormalities in several ectodermal structures including skin i.

Ectrodactyly-ectodermal dysplasia clefting syndrome (EEC syndrome)

According to Blauth and Borisch[ 15 ] six level radiographic classification of cleft feet, the right foot is Grade II, as there are five metatarsals, which are partially hypoplastic or synostotic with other metatarsals or phalanges.

Chromosomes, which are present in the nucleus of human cells, carry the genetic information for each individual. EEC syndrome and ectrodacctyly-ectodermal anomalies: But absence of ectrodactyly differentiates it form EEC syndrome. Twenty-four cases of the EEC syndrome: Analysis of the p63 gene in classical EEC syndrome, related syndromes, and non-syndromic orofacial clefts. Saliva[ 23 ] substitutes can be used in cases of severe xerostomia.

More than cases dysplasia-cleftihg been described in the literature. Using transvaginal ultrasonography, Bronshtein and Gershoni-Baruch diagnosed bilateral cleft lip and lobster-claw deformities of the hands and feet, consistent with the diagnosis of the EEC syndrome, dysplasia-cleftinng a week-old fetus.

In most patients, the cleft lip and palate are surgically repaired early in life to address the issues with nutrition and speech. For information about clinical trials sponsored by private sources, contact: Making a diagnosis of ED is challenging as any ectodermal derivative may be involved in varying degrees, and other systems may also be affected.

Cleft palate-lip, hare lip, dacryocystitis, and cleft hand and foot. Contemp Clin Dent ;3: Case Report A year-old man presented to our unit with a chief complaint of cleft lip and cleft palate.

There is no test for germline mosaicism before pregnancy. Syndromes of the Head and Neck.


Tooth decay dental caries is common and often severe. We present a case of a year-old boy with EEC syndrome and offer insight into current knowledge about this syndrome.

Ectrodactyly-ectodermal dysplasia clefting syndrome (EEC syndrome)

In addition to ectodermal, neuroectodermal and mesectodermal derivatives are often found. A test known as chorionic villi sampling can also be used to obtain a prenatal diagnosis of EEC syndrome in these cases. Please review our privacy policy.

The patient reported for follow-up on a regular basis for a period of six months [Figure 6]. Emollients may be used to treat dry skin.

A complete ophthalmological exam will be performed to detect potential eye complications associated with the disorder such as lacrimal duct obstruction. The p63 gene in EEC and other syndromes.


Orphanet: EEC syndrome

The hypohydrotic symptoms of ectodermal dysplasia described above are evidenced not only in the skin of affected individuals, but also in their phonation and voice production. By clinical examination and history, she had recurrent dacryocystitis and a chronic, mild, purulent eye discharge, mainly after sleep.

This striking data offers convincing support for the p63 gene hypothesis.

Mutations of this gene lead to a reduction of functional levels of normally functioning P63 protein which interferes the proper development of these structures. The description of the mice ectrodacytly-ectodermal as follows:. Genetic counseling may be of benefit for affected individuals and their families. Despite some of the syndromes having different genetic causes, the symptoms are sometimes similar. Prenatal transvaginal diagnosis of the ectrodactyly, ectodermal dysplasia, cleft palate EEC syndrome.
