Audiogenic seizure susceptibility was studied in mice segregating for the microphthalmic white gene (Miwh). Previous work by Deol had indicated that mice with either one or two Miwh alleles had severe inner ear defects. A congenic inbred strain provided mice that were identical in genetic background
Microphthalmia is an important developmental eye disorder. Although mutations in several genes have been linked to this condition, they only account for a minority of cases. We performed autozygome analysis and exome sequencing on a multiplex consanguineous family in which colobomatous
OBJECTIVE
To delineate the features of a novel neurodegenerative disease.
METHODS
We report three children of three related families with congenital microphthalmia and blindness, and progressive spasticity, microcephaly, seizures, and profound mental retardation.
RESULTS
A magnetic resonance imaging
A one-month-old infant boy was examined early in life because his mother had bilateral retinoblastoma and his father had bilateral microphthalmia. The ophthalmologist found his right eye was normal size with a coloboma of the iris, choroid, and retina. The left eye was microphthalmic with a coloboma
We report a case of 13-year-old girl with short stature, microcephalus, blepharophimosis, ptosis, bilateral microphthalmia (more prominent in the right), hypogonadism, other minor anomalies, and severe mental retardation. Her mother had two spontaneous abortions. She was born as the second baby of
Microphthalmia with linear skin defects syndrome is an X-linked dominant disorder characterized by microphthalmia and other ocular anomalies as well as linear, jagged skin defects typically involving the scalp, face, neck, and upper trunk. Other associated characteristics include short stature,
We present a 4-year-old girl with a maternally derived, unbalanced X;3 translocation resulting in partial Xp monosomy and partial 3p trisomy. She had chorioretinal defects, developmental delay, infantile seizures, and microphthalmia. These findings initially suggested a diagnosis of Aicardi
Anophthalmia/microphthalmia (A/M) is a genetically heterogeneous birth defect for which the etiology is unknown in more than 50% of patients. We used exome sequencing with the ACE Exome(TM) (Personalis, Inc; 18 cases) and UCSF Genomics Core (21 cases) to sequence 28 patients with A/M and four
BACKGROUND
Lenz microphthalmia syndrome (LMS) is a genetically heterogeneous X-linked disorder characterised by microphthalmia/anophthalmia, skeletal abnormalities, genitourinary malformations, and anomalies of the digits, ears, and teeth. Intellectual disability and seizure disorders are seen in
Hypoparathyroidism-retardation-dysmorphism (HRD; Sanjad-Sakati Syndrome; Online Mendelian Inheritance in Man [OMIM] #241410) is a rare recessive syndrome predominantly seen on the Arabian Peninsula and characterized by congenital hypoparathyroidism, intrauterine growth retardation, mental
We describe a 20-year-old 46,XY woman, with clinical findings of Fraser syndrome and three mitochondrial DNA (mtDNA) mutations of Leber hereditary optic neuropathy. The patient had microphthalmia, blindness, widely spaced nipples, bifid ureter, syndactyly of the toes, and mental retardation.
The oculocerebrocutaneous (OCC) syndrome is characterized by the presence of orbital cysts and microphthalmia/anophthalmia, focal hypo- and aplastic skin defects, skin appendages and cerebral malformations. Most of the patients suffer from psychomotor retardation and seizures. To date, 23 patients
BACKGROUND
Wolf-Hirschhorn syndrome (WHS) multiple congenital anomalies/mental retardation is caused by partial deletion of the short arm of chromosome 4 and can be considered a contiguous gene syndrome, characterized by typical facial appearance, mental retardation, growth delay, and
BACKGROUND
Early fetal herpes simplex virus (HSV) infection is rarely documented. Only the minority of affected fetuses survive this condition.
METHODS
At 19 weeks of gestation the first episode of a genital HSV-infection of a pregnant woman was treated with local interferon beta. At 34 weeks of
