Summaries for Microphthalmia, Syndromic 2

UniProtKB/Swiss-Prot : 75 Microphthalmia, syndromic, 2: A very rare multiple congenital anomaly syndrome characterized by eye anomalies (congenital cataract, microphthalmia, or secondary glaucoma), facial abnormalities (long narrow face, high nasal bridge, pointed nose with cartilages separated at the tip, cleft palate, or submucous cleft palate), cardiac anomalies (atrial septal defect, ventricular septal defect, or floppy mitral valve) and dental abnormalities (canine radiculomegaly, delayed dentition, oligodontia, persistent primary teeth, or variable root length). Microphthalmia is a disorder of eye formation, ranging from small size of a single eye to complete bilateral absence of ocular tissues (anophthalmia). In many cases, microphthalmia/anophthalmia occurs in association with syndromes that include non-ocular abnormalities.

MalaCards based summary : Microphthalmia, Syndromic 2, also known as oculofaciocardiodental syndrome, is related to anophthalmos with limb anomalies and microphthalmia, syndromic 1, and has symptoms including unspecified visual loss An important gene associated with Microphthalmia, Syndromic 2 is BCOR (BCL6 Corepressor), and among its related pathways/superpathways is Signaling events mediated by HDAC Class II. Affiliated tissues include heart, eye and kidney, and related phenotypes are genu valgum and ptosis

Genetics Home Reference : 25 Oculofaciocardiodental (OFCD) syndrome is a condition that affects the development of the eyes (oculo-), facial features (facio-), heart (cardio-) and teeth (dental). This condition occurs only in females.

NIH Rare Diseases : 53 Oculofaciocardiodental syndrome is a genetic syndrome that affects the eyes, heart, face, and teeth. Common signs and symptoms include abnormally small deep-set eyes, cataracts, long narrow face, a broad nasal tip that is divided by a cleft, heart defects, and teeth with very large roots. Other signs and symptoms include glaucoma, cleft palate, delayed loss of baby teeth, missing or abnormally small teeth, misaligned teeth, and defective tooth enamel. Eye symptoms may involve one or both eyes.Oculofaciocardiodental syndrome is caused by mutations in the BCOR gene and is inherited in an X-linked dominant fashion.
