Microcephaly lymphoedema chorioretinal dysplasia also known as lymphedema microcephaly chorioretinopathy syndrome [1] is a rare genetic condition associated with:

Contents

In 1992, Feingold and Bartoshesky described two unrelated children with microcephaly, lymphoedema and chorioretinal dysplasia (MIM 152950) as a distinct entity. Since then there have been further reports of children with these three features (Angle et al. 1994, Fryns et al. 1995, Limwongse et al. 1999, Casteels et al. 2001)

Children have also been seen with two of the above features:

Presentation

The distinct facial feature include upslanting palpebral fissures, a broad nose with rounded tip, long philtrum with a thin upper lip, pointed chin and prominent ears (Vasudevan 2005)

Genetics

The former (microcephaly and lymphoedema) has been described as an autosomal dominant (MIM 156590) or X-linked trait, while the latter (microcephaly and chorioretinal dysplasia) has been described as autosomal dominant, autosomal recessive (MIM 251270 or Mirhosseini-Holmes-Walton syndrome) or X-linked trait.

Macrocephaly is a condition in which circumference of the human head is abnormally large. It may be pathological or harmless, and can be a familial genetic characteristic. People diagnosed with macrocephaly will receive further medical tests to determine whether the syndrome is accompanied by particular disorders. Those with benign or familial macrocephaly are considered to have megalencephaly.

Popliteal pterygium syndrome (PPS) is an inherited condition affecting the face, limbs, and genitalia. The syndrome goes by a number of names including the popliteal web syndrome and, more inclusively, the facio-genito-popliteal syndrome. The term PPS was coined by Gorlin et al. in 1968 on the basis of the most unusual anomaly, the popliteal pterygium.

Raine syndrome (RNS), also called osteosclerotic bone dysplasia, is a rare autosomal recessive congenital disorder characterized by craniofacial anomalies including microcephaly, noticeably low set ears, osteosclerosis, a cleft palate, gum hyperplasia, a hypoplastic nose, and eye proptosis. It is considered to be a lethal disease, and usually leads to death within a few hours of birth. However, a recent report describes two studies in which children with Raine syndrome have lived to 8 and 11 years old, so it is currently proposed that there is a milder expression that the phenotype can take.

Floating–Harbor syndrome, also known as Pelletier–Leisti syndrome, is a rare disease with fewer than 50 cases described in the literature. It is usually diagnosed in early childhood and is characterized by the triad of proportionate short stature with delayed bone age, characteristic facial appearance, and delayed speech development. Although its cause is unknown, it is thought to result from genetic mutation, and diagnosis is established by the presence of a heterozygous SRCAP mutation in those with clinical findings of FHS.

Focal facial dermal dysplasia is a rare genetically heterogeneous group of disorders that are characterized by congenital bilateral scar like facial lesions, with or without associated facial anomalies. It is characterized by hairless lesions with fingerprint like puckering of the skin, especially at the temples, due to alternating bands of dermal and epidermal atrophy.

Acro–dermato–ungual–lacrimal–tooth syndrome is a rare genetic disease. It is an autosomal dominant form of ectodermal dysplasia, a group of disorders that affects the hair, teeth, nails, sweat glands, and extremities. The syndrome arises from a mutation in the TP63 gene. This disease was previously thought to be a form of ectrodactyly–ectodermal dysplasia–cleft syndrome (EEC), but was classified as a different disease in 1993 by Propping and Zerres.

Ischiopatellar dysplasia is a rare autosomal dominant disorder characterized by a hypoplasia of the patellae as well as other bone anomalies, especially concerning the pelvis and feet. It is also known as small patella syndrome, with earlier synonyms being Scott-Taor syndrome, Coxo-podo-patellar syndrome, Patella aplasia, coxa vara, tarsal synostosis, Congenital coxa vara, patella aplasia and tarsal synostosis ischiocoxopodopatellar syndrome.
