Cognitive impairment, and Craniosynostosis

Low match ISOLATED CLOVERLEAF SKULL SYNDROME

Isolated cloverleaf skull syndrome is a form of craniosynostosis involving multiple sutures (coronal, lambdoidal, sagittal and metopic ) characterized by a trilobular skull of varying severity (frontal towering and bossing, temporal bulging and a flat posterior skull), dysmorphic features (downslanting palpebral fissures, midface hypoplasia, and extreme proptosis) and that is complicated by hydrocephalus, cerebral venous hypertension, developmental delay/intellectual disability and hind brain herniation.

Low 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.

Gabriele-de Vries syndrome is an autosomal dominant neurodevelopmental disorder characterized by delayed psychomotor development, variable cognitive impairment, often with behavioral problems, feeding problems, some movement abnormalities, and dysmorphic facial features. Affected individuals may also have a variety of congenital abnormalities (summary by Gabriele et al., 2017).

Low match ANTLEY-BIXLER SYNDROME WITHOUT GENITAL ANOMALIES OR DISORDERED STEROIDOGENESIS; ABS2

The Antley-Bixler syndrome (ABS) is an exceptionally rare craniosynostosis syndrome characterized by radiohumeral synostosis present from the perinatal period. There is a wide spectrum of anomalies seen in ABS, including midface hypoplasia, choanal stenosis or atresia, and multiple joint contractures. Mortality has been reported to be as high as 80% in the neonatal period, primarily due to airway compromise, and prognosis improves with increasing age (summary by McGlaughlin et al., 2010).

Low match 1P31P32 MICRODELETION SYNDROME

1p31p32 microdeletion syndrome is a rare chromosomal anomaly syndrome, resulting from the partial deletion of the short arm of chromosome 1, characterized by developmental delay, corpus callosum agenesis/hypoplasia and craniofacial dysmorphism, such as macrocephaly (caused by hydrocephalus or ventriculomegaly), low-set ears, anteverted nostrils and micrognathia. Urinary tract defects (e.g. vesicoureteral reflux, urinary incontinence) are also frequently associated. Other reported variable manifestations include hypotonia, tethered spinal cord, Chiari type I malformation and seizures.

Low match 3MC SYNDROME 2; 3MC2

The term '3MC syndrome' encompasses 4 rare autosomal recessive disorders that were previously designated the Carnevale, Mingarelli, Malpuech, and Michels syndromes, respectively. The main features of these syndromes are facial dysmorphism that includes hypertelorism, blepharophimosis, blepharoptosis, and highly arched eyebrows, which are present in 70 to 95% of cases. Cleft lip and palate, postnatal growth deficiency, cognitive impairment, and hearing loss are also consistent findings, occurring in 40 to 68% of cases. Craniosynostosis, radioulnar synostosis, and genital and vesicorenal anomalies occur in 20 to 30% of cases. Rare features include anterior chamber defects, cardiac anomalies, caudal appendage, umbilical hernia (omphalocele), and diastasis recti (summary by Rooryck et al., 2011).For a discussion of genetic heterogeneity of 3MC syndrome, see 3MC1 (OMIM ).
