High match CARDIOFACIOCUTANEOUS SYNDROME 2; CFC2

Cardiofaciocutaneous (CFC) syndrome is a multiple congenital anomaly disorder characterized by a distinctive facial appearance, heart defects, and mental retardation (summary by Niihori et al., 2006). In a phenotypic comparison of BRAF (OMIM )-positive and KRAS-positive individuals with CFC, Niihori et al. (2006) observed that patients with KRAS mutations did not have the skin abnormalities, such as ichthyosis, hyperkeratosis, and hemangioma, that were present in patients with BRAF mutation.

High match NOONAN SYNDROME 3; NS3

Noonan syndrome is an autosomal dominant dysmorphic syndrome characterized primarily by dysmorphic facial features, cardiac abnormalities, and short stature, among other features (summary by Shah et al., 1999).For a phenotypic description and a discussion of genetic heterogeneity of Noonan syndrome, see NS1 (OMIM ), which is caused by mutations in the PTPN11 gene (OMIM ). Approximately 50% of cases of Noonan syndrome are caused by mutations in PTPN11.

High match EHLERS-DANLOS SYNDROME, MUSCULOCONTRACTURAL TYPE, 2; EDSMC2

The musculocontractural type of Ehlers-Danlos syndrome is characterized by progressive multisystem fragility-related manifestations, including joint dislocations and deformities; skin hyperextensibility, bruisability, and fragility, with recurrent large subcutaneous hematomas; cardiac valvular, respiratory, gastrointestinal, and ophthalmologic complications; and myopathy, featuring muscle hypoplasia, muscle weakness, and an abnormal muscle fiber pattern in histology in adulthood, resulting in gross motor developmental delay (summary by Muller et al., 2013).For a discussion of genetic heterogeneity of the musculocontractural type of Ehlers-Danlos syndrome, see EDSMC1 (OMIM ).

High match PROGEROID AND MARFANOID ASPECT-LIPODYSTROPHY SYNDROME

Progeroid and marfanoid aspect-lipodystrophy syndrome is a rare systemic disease characterized by a neonatal progeroid appearance (not associated with other manifestations of premature aging) associated with facial dysmorphism (e.g. macrocephaly or arrested hydrocephaly, proptosis, downslanting palpebral fissures, retrognathia), generalized, extreme, congenital lack of subcutaneous fat tissue (except in the breast and iliac region) and incomplete signs of Marfan syndrome (mainly severe myopia, joint hyperextensibility and arachnodactyly). Metabolic disturbances are not associated.

High match GLOBAL DEVELOPMENTAL DELAY, ABSENT OR HYPOPLASTIC CORPUS CALLOSUM, AND DYSMORPHIC FACIES; GDACCF

GDACCF is an intellectual disability syndrome apparent soon after birth with neonatal hypotonia, poor feeding, and respiratory insufficiency followed by delayed psychomotor development and intellectual disability with poor speech. Brain imaging shows aplasia or hypoplasia of the corpus callosum. Affected individuals have variable dysmorphic facial features, and some may have dysplastic, cystic kidneys or mild cardiac defects (summary by Stevens et al., 2016).

High match TALL STATURE-INTELLECTUAL DISABILITY-RENAL ANOMALIES SYNDROME

Thauvin-Robinet-Faivre syndrome is an autosomal recessive disorder characterized by generalized overgrowth, mainly of height, and mildly delayed psychomotor development with mild or severe learning difficulties. More variable features may include congenital heart defects, kidney abnormalities, and skeletal defects. Patients may have an increased risk for Wilms tumor (summary by Akawi et al., 2016).

High match NEONATAL MARFAN SYNDROME

Neonatal Marfan syndrome is a rare, severe and life-threatening genetic disease, occuring during the neonatal period, characterized by classical Marfan syndrome manifestations in addition to facial dysmorphism (megalocornea, iridodonesis, ectopia lentis, crumpled ears, loose redundant skin giving a 'senile' facial appearance), flexion joint contractures, pulmonary emphysema, and a severe, rapidly progressive cardiovascular disease (including ascending aortic dilatation and severe mitral and/or tricuspid valve insufficiency). Additionally, skeletal manifestations (arachnodactyly, dolichostenomelia, pectus deformities) are also associated.

High match LOEYS-DIETZ SYNDROME 5; LDS5

Loeys-Dietz syndrome-5 (LDS5), also known as Rienhoff (pronounced REENhoff) syndrome, is characterized by syndromic presentation of aortic aneurysms involving the thoracic and/or abdominal aorta, with risk of dissection and rupture. Other systemic features include cleft palate, bifid uvula, mitral valve disease, skeletal overgrowth, cervical spine instability, and clubfoot deformity; however, not all clinical features occur in all patients. In contrast to other forms of LDS (see {609192}), no striking aortic or arterial tortuosity is present in these patients, and there is no strong evidence for early aortic dissection (summary by Bertoli-Avella et al., 2015).For a general phenotypic description and a discussion of genetic heterogeneity of Loeys-Dietz syndrome, see LDS1 (OMIM ).
