Cryptorchidism, and Neonatal hypotonia

Severe hypotonia-psychomotor developmental delay-strabismus-cardiac septal defect syndrome is a rare, genetic, non-dystrophic congenital myopathy disorder characterized by a neonatal-onset of severe generalized hypotonia associated with mild psychomotor delay, congenital strabismus with abducens nerve palsy, and atrial and/or ventricular septal defects. Cryptorchidism is commonly reported in male patients and muscle biopsy typically reveals increased variability in muscle fiber size.

MDDGB2 is an autosomal recessive congenital muscular dystrophy associated with mental retardation and mild structural brain abnormalities (Yanagisawa et al., 2007). It is part of a group of similar disorders, collectively known as 'dystroglycanopathies,' resulting from defective glycosylation of alpha-dystroglycan (DAG1 ) (Godfrey et al., 2007).For a discussion of genetic heterogeneity of congenital muscular dystrophy-dystroglycanopathy type B, see MDDGB1 (OMIM ).

Corpus callosum agenesis-abnormal genitalia syndrome is a rare, genetic developmental defect during embryogenesis syndrome characterized by agenesis of the corpus callosum, mild to severe neurological manifestations (intellectual disability, developmental delay, epilepsy, dystonia), and urogenital anomalies (hypospadias, cryptorchidism, renal dysplasia, ambiguous genitalia). Additionally, skeletal anomalies (limb contractures, scoliosis), dysmorphic facial features (prominent supraorbital ridges, synophris, large eyes) and optic atrophy have been observed.

Intellectual disability-feeding difficulties-developmental delay-microcephaly syndrome is a rare, genetic, syndromic intellectual disability disorder characterized by borderline to severe intellectual disability, global development delay, feeding difficulties, microcephaly, short stature and mild facial dysmorphism, including thick eyebrows, long eyelashes, prominent incisors and/or thin upper lip. Other associated features may include hypermetropia with or without esotropia, behavioral anomallies (e.g. autistic behavior, sleeping disturbances), urogenital abnormalities (e.g. crytorchidism, inguinal hernia), single palmar crease, fifth-finger clinodactyly and cardiac defects (e.g. ASD, PDA).

Hartsfield syndrome is a rare, genetic, developmental defect during embryogenesis malformation syndrome characterized by the association of variable degrees of holoprosencephaly and uni- or bilateral ectrodactyly of the hands and/or feet. Additional variable features, including facial dysmorphism (e.g. hypertelorism, short bulbous nose, long philtrum, dysplastic/low-set ears, cleft lip and palate, tented upper lip), other brain malformations (such as corpus callosum agenesis, absent septum pellucidum, absent olfactory bulbs/tracts, vermian hypoplasia), pituitary gland-related endocrine disorders (e.g. central diabetes insipidus, hypogonadotropic hypogonadism) and hypothalamic dysfunction, may be associated.
