1qter deletion syndrome is a chromosomal anomaly characterized by an intellectual deficiency, progressive microcephaly, seizures, growth delay, distinct facial dysmorphic features and various midline defects including cardiac, corpus callosum, gastro-oesophalgeal and urogenital anomalies.
DISTAL MONOSOMY 1Q Is also known as telomeric deletion 1q|distal deletion 1q|monosomy 1qter

Intellectual developmental disorder with neuropsychiatric features is an autosomal recessive disorder characterized by moderate intellectual disability, relatively mild seizures, and neuropsychiatric abnormalities, such as anxiety, obsessive-compulsive behavior, and autistic features. Mild facial dysmorphic features may also be present (summary by Srour et al., 2017).

More info about BLEPHAROPHIMOSIS-INTELLECTUAL DISABILITY SYNDROME, MKB TYPEHCFP3 is an autosomal recessive congenital cranial dysinnervation disorder characterized by isolated dysfunction of the seventh cranial nerve resulting in facial palsy. Additional features may include orofacial anomalies, such as smooth philtrum, lagophthalmos, swallowing difficulties, and dysarthria, as well as hearing loss. There is some phenotypic overlap with Moebius syndrome (see, e.g., {157900}), but patients with HCFP usually retain full eye motility or have esotropia without paralysis of the sixth cranial nerve (summary by Vogel et al., 2016).For a phenotypic description and a discussion of genetic heterogeneity of hereditary congenital facial paresis, see {601471}.

Early infantile epileptic encephalopathy-64 is a neurodevelopmental disorder characterized by onset of seizures usually in the first year of life and associated with intellectual disability, poor motor development, and poor or absent speech. Additional features include hypotonia, abnormal movements, and nonspecific dysmorphic features. The severity is variable: some patients are unable to speak, walk, or interact with others as late as the teenage years, whereas others may have some comprehension (summary by Straub et al., 2018).For a general phenotypic description and a discussion of genetic heterogeneity of EIEE, see EIEE1 (OMIM ).

Intellectual disability-facial dysmorphism syndrome due to SETD5 haploinsufficiency is a rare, syndromic intellectual disability characterized by intellectual disability of various severity, hypotonia, feeding difficulties, dysmorphic features, autism and behavioral issues. Growth retardation, congenital heart anomalies, gastrointestinal and genitourinary defects have been rarely associated.

AL KAISSI SYNDROME; ALKAS Is also known as growth retardation, spine malformation, dysmorphic facies, and developmental delay

Cornelia de Lange syndrome is a multisystem developmental disorder characterized by distinctive facial dysmorphism, pre- and postnatal growth failure, delayed psychomotor development and intellectual disability, hypertrichosis, and sometimes distal limb malformations (summary by Gil-Rodriguez et al., 2015).For a phenotypic description and a discussion of genetic heterogeneity of Cornelia de Lange syndrome, see {122470}.

Ayme-Gripp syndrome is a clinically homogeneous phenotype characterized by congenital cataracts, sensorineural hearing loss, intellectual disability, seizures, brachycephaly, a distinctive flat facial appearance, and reduced growth (Niceta et al., 2015).
AYME-GRIPP SYNDROME; AYGRP Is also known as cataracts, congenital, with sensorineural deafness, down syndrome-like facial appearance, short stature, and mental retardation

Ornithine transcarbamylase deficiency is an X-linked inborn error of metabolism of the urea cycle which causes hyperammonemia. The disorder is treatable with supplemental dietary arginine and low protein diet.Urea cycle disorders are characterized by the triad of hyperammonemia, encephalopathy, and respiratory alkalosis. Five disorders involving different defects in the biosynthesis of the enzymes of the urea cycle have been described: OTC deficiency, carbamyl phosphate synthetase deficiency (OMIM ), argininosuccinate synthetase deficiency, or citrullinemia (OMIM ), argininosuccinate lyase deficiency (OMIM ), and arginase deficiency (OMIM ).
