Family history and clefting as major criteria for CHARGE syndrome.

CHARGE syndrome is an autosomal dominant malformation syndrome associated with mutations in CHD7. The condition is typically sporadic with few familial cases reported. The diagnosis of CHARGE syndrome is based on a combination of major and minor criteria comprised of structural and functional abnormalities, most of which are part of the original CHARGE acronym, although additional anomalies have been added.

Aggressive juvenile polyposis in children with chromosome 10q23 deletion.

Juvenile polyps are relatively common findings in children, while juvenile polyposis syndrome (JPS) is a rare hereditary syndrome entailing an increased risk of colorectal cancer. Mutations in BMPR1A or SMAD4 are found in roughly half of patients diagnosed with JPS. Mutations in PTEN gene are also found in patients with juvenile polyps and in Bannayan-Riley-Ruvalcaba syndrome and Cowden syndrome.

Genotypic and phenotypic analysis of 396 individuals with mutations in Sonic Hedgehog.

Background: Holoprosencephaly (HPE), the most common malformation of the human forebrain, may result from mutations in over 12 genes. Sonic Hedgehog (SHH) was the first such gene discovered; mutations in SHH remain the most common cause of non-chromosomal HPE. The severity spectrum is wide, ranging from incompatibility with extrauterine life to isolated midline facial differences.

Petty syndrome and Fontaine-Farriaux syndrome: Delineation of a single syndrome.

In 1990, Petty et al. described two patients representing a novel syndrome with "congenital progeriod" features and neither had classical progeria nor Wiedemann-Rautenstrauch syndrome, though many findings were overlapping. One of the cases had previously been described by Dr.

Comprehensive ZEB2 gene analysis for Mowat-Wilson syndrome in a North American cohort: a suggested approach to molecular diagnostics.

Mowat-Wilson syndrome is a genetic condition characterized by a recognizable facial phenotype in addition to moderate to severe cognitive disability with severe speech impairment and variable multiple congenital anomalies. The anomalies may include Hirschsprung disease, heart defects, structural eye anomalies including microphthalmia, agenesis of the corpus callosum, and urogenital anomalies. Microcephaly, seizure disorder and constipation are common.

The Hunter-MacDonald syndrome with expanded phenotype including risk of meningioma: an update and review.

Hunter-MacDonald syndrome (HMS) is a rare, autosomal dominant skeletal dysplasia with multiple malformations. The skeletal manifestations of HMS include short stature, scoliosis, epiphyseal dysplasia with early osteoarthritis leading to joint replacement, prominent humeral insertions for the deltoids, camptodactyly, subluxation of the thumbs, and malformed feet. Craniofacial manifestations include normal head circumference, tall forehead, bitemporal narrowing, ptosis, short palpebral fissures, and short philtrum.

Expanding the phenotype of oculoectodermal syndrome: possible relationship to encephalocraniocutaneous lipomatosis.

Oculoectodermal syndrome (OES) is characterized by epibulbar dermoids, aplasia cutis congenita, and other abnormalities. Here, we report 2 new cases, review 13 previous cases, and propose that OES may be a mild variant of encephalocraniocutaneous lipomatosis (ECCL), differing primarily in its lack of intracranial pathology.

Mutations in IRF6 cause Van der Woude and popliteal pterygium syndromes.

Interferon regulatory factor 6 (IRF6) belongs to a family of nine transcription factors that share a highly conserved helix-turn-helix DNA-binding domain and a less conserved protein-binding domain. Most IRFs regulate the expression of interferon-alpha and -beta after viral infection, but the function of IRF6 is unknown. The gene encoding IRF6 is located in the critical region for the Van der Woude syndrome (VWS; OMIM 119300) locus at chromosome 1q32-q41 (refs 2,3).
