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 management of this syndrome is challenging, with few reports in the medical literature.

Ectrodactyly–ectodermal dysplasia–cleft syndrome – Wikipedia

Most had blonde, sparse hair with slow growth, thin nails, periorbital hyperpigmentation, and dental caries. Epithelium refers to specific tissue that lines many of the cavities and structures within the body such as the bladder. Genetic counseling may be of benefit for affected individuals and their families.

The study is known as the p63 knockout mice study, in which the phenotypes of pdeficient mice are described.

Further genetic research is necessary to identify and rule out other possible loci contributing to EEC syndrome, though it seems certain that disruption of the p63 gene is involved to some extent. EEC syndrome, argto-gln TP63 mutation and micturition difficulties: Children with hypohidrosis should be monitored closely for signs of hyperthermia, particularly during periods of prolonged activity and or during summer months.

There was no dermatitis of the scalp. Table 2 Schirmer test. The TP63 gene contains instructions for synthesizing encoding a protein that is essential for the proper development of the limbs and structures derived from the ectoderm. University of Washington, Seattle; Schirmer test determined the amount of tear production and showed less than normal values i.


CC ]. Alone we are rare. Choanal atresia as a feature of ectrodactyly-ectodermal dysplasia-clefting EEC syndrome. Rodini and Richieri-Costa reported on 20 Brazilian patients 11 sporadic and 9 familial and gave a review of 13 disorders to be considered in the differential diagnosis: A bonus to all MIMmatch users is the option to sign up for updates on new gene-phenotype relationships.

Interfamilial variability ectrodactyly-ectosermal significantly greater than intrafamilial variability, pointing to genetic allelic? Ectrldactyly-ectodermal disorder formerly designated EEC syndrome type 2 no longer exists. Am J Med Genet A. Most cases of EEC syndrome are caused by mutations of the TP63 gene and are either new spontaneous mutations or are inherited as autosomal dominant disorders.

The right hand showed clefting between the second and fourth digits with the absence of the third digit. Biopsies of the bladder demonstrated very thin atrophic bladder epithelium. Surgery may also be necessary for blocked lacrimal ducts.

Proposals for a new classification based on roentgenographic morphology. Feingold syndrome Saethre—Chotzen syndrome.

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

Choanal atresia as a feature of ectrodactyly-ectodermal dysplasia-clefting EEC ectrodactyly-ectkdermal The symptoms of EEC syndrome are highly variable, even among members of the same family. Abnormality of the sweat glands can lead to a reduced ability to sweat hypohidrosiswhich can be associated with heat intolerance and fever.


The ectodermal dysplasia associated with EEC syndrome arises from abnormalities in the embryonic ectoderm, as described above. Archives of Otolaryngology Chicago, Ill. Article Access Statistics Viewed: In addition, genetic research with an emphasis on genetic syndrome differentiation should prove to ectrosactyly-ectodermal very useful in distinguishing between syndromes that present with very similar clinical findings.

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

Some cases ddysplasia-clefting EEC may be due to Gondal Mosaicism or Germilne Mosaicism, a condition in which some of the reproductive cells germ cells carry the mutations, while others contain a normal cell line Mosaicism. A variety of tests may be used to evaluate individuals with EEC syndrome.

Was she a germinal somatic mosaic for the dominant mutation? The type and severity of ectodermal dysplasia in individuals with EEC syndrome is highly variable.

Ectrodactyly-ectodermal dysplasia clefting syndrome (EEC syndrome)

There is considerable overlap among these disorders and some researchers consider them different expressions of one disease process. Ectrodactyly-ectodermal dysplasia-clefting EEC syndrome: He had gray hair on the right half of his scalp and brown thin hair on the left side.
