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).

Other associated clinical features include abnormalities of the genitourinary system i. All four hands and feet may be affected in some individuals. There is median cleft in the hands and feet due to the absence of central rays giving ectrodactyly-ectidermal to lobster. Views Read Edit View history.

Orphanet: EEC syndrome

Two cases in which the skin, nails and teeth were very imperfectly developed. AntenatalNeonatal ICD EEC syndrome a genetic developmental disorder distinctly featuring ectrodactyly, ectodermal dysplasia and facial clefts may also be noticed with characterstics like recurrent urinary tract infections, vesiculioureteral reflux, photobia, anomalies of kidney, hearing loss and speech defects.

Isolated cases were more severely affected than familial cases. Table 2 Schirmer test.

An endeavor should be made to establish a protocol for the treatment of EEC syndrome to minimize progression of the deformities. A study supports the dysplaeia-clefting of the p63 gene as the locus for the mutations associated with EEC syndrome.


Pairs of human chromosomes ectrodactyly-ectodegmal numbered from 1 through 22 and the sex chromosomes are designated X and Y. This section with questionable factual accuracy needs more medical references for verification or relies too heavily on primary sources. CC ].

This syndrome has three main symptoms, which display variable expression and penetrance. EEC type 2 does not exist anymore. Similar remarkable improvement was achieved with the use of the synthetic sulfonated glycosaminoglycan.

Ectrodactyly – ectodermal dysplasia – cleft lip/palate syndrome: a rare entity

Support Center Support Center. Ectodermal dysplasias associated with clefting: Some individuals may develop glandular abnormalities such as an underdeveloped thymus and reduced activity of the pituitary gland hypopituitarism.

The Rapp-Hodgkin syndrome results from mutations of the TP63 gene. The symptoms of EEC syndrome are highly variable, even among members of the same family. A trial with a synthetic sulfonated glycosaminoglycan resulted in remarkable improvement with almost complete disappearance of complaints.

Summary ddysplasia-clefting related texts. Dental surgery and corrective devices may be used to treat misshapen teeth. They suggested that there is an association with isolated growth hormone deficiency, the latter being secondary to developmental hypothalamic defects. Group A includes those disorders with signs affecting at least two of the classical structures: Most cases of EEC syndrome are caused by mutations of the TP63 gene and are either new spontaneous mutations ectrodactyly-fctodermal are inherited as autosomal dominant disorders.


Although speech therapy was prescribed, the patient did not return for treatment. The parents reported that he seldom sweated.

Ectrodactyly–ectodermal dysplasia–cleft syndrome – Wikipedia

Neuroectodermal derivatives that can be affected include sensory placodes, cutaneous pigmental cells, and hair buds. This study is also cited in the demonstration that the growth and patterning of the underlying mesenchyme is highly dependent on the apical ectodermal ridge of the limbs, as well as the maxillary and mandibular branchial ectoderm that are so prominently disturbed in these mice.

Genetic disorderprotein biosynthesis: More recently, the p63 gene has been targeted in numerous studies. There is considerable overlap among these disorders and some researchers consider them different expressions of one disease process.

Report of 8 cases.
