The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 178364DefinitionSyndromic microphthalmia, type 5 is characterized by the association of a range of ocular anomalies (anophthalmia, microphthalmia and retinal abnormalities) with variable developmental delay and central nervous system malformations.EpidemiologyLess than 20 cases have been reported in the literature so far.Clinical descriptionThe clinical picture is highly variable, even between affected members of the same family. Ocular findings ranged from bilateral anophthalmia, to severe or mild bi- or unilateral microphthalmia and retinal dystrophy. MRI may reveal optic nerve aplasia/hypoplasia, hippocampal malformations, structural abnormalities of the pituitary gland, and agenesis of the corpus callosum. Severe developmental delay was noted in some patients, whilst others showed normal cognitive development. Pituitary dysfunction, leading to growth hormone deficiency and short stature, or combined pituitary hormone deficiency (CPHD), has also been reported.EtiologyThe syndrome is caused by heterozygous mutations in the OTX2 gene (14q22.3).Differential diagnosisA similar phenotype with bilateral anophthalmia and pituitary abnormalities (with additional findings of limb defects, ear anomalies and facial dysmorphism) is found in patients carrying a deletion encompassing the OTX2 gene. Patients with the full clinical spectrum of ocular anomalies, central nervous system abnormalities and pituitary abnormalities also show significant overlap with septooptic dysplasia (see this term).Visit the Orphanet disease page for more resources.
MalaCards based summary : Microphthalmia, Syndromic 5, also known as syndromic microphthalmia type 5, is related to coloboma of macula and fryns microphthalmia syndrome. An important gene associated with Microphthalmia, Syndromic 5 is OTX2 (Orthodenticle Homeobox 2). Affiliated tissues include pituitary and eye, and related phenotypes are short stature and cleft palate Disease Ontology : 12 A syndromic microphthalmia characterized by unilateral or bilateral microphthalmia or clinical anophthalmia and variable additional features that has material basis in heterozygous mutation in OTX2 on chromosome 14q22.3. UniProtKB/Swiss-Prot : 73 Microphthalmia, syndromic, 5: Patients manifest unilateral or bilateral microphthalmia/clinical anophthalmia and variable additional features including pituitary dysfunction, coloboma, microcornea, cataract, retinal dystrophy, hypoplasia or agenesis of the optic nerve, agenesis of the corpus callosum, developmental delay, joint laxity, hypotonia, and seizures. 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. Retinal dystrophy, early-onset, with or without pituitary dysfunction: An autosomal dominant ocular disease characterized by pattern dystrophy of the retinal pigment epithelium, and photoreceptor degeneration. Mild developmental anomalies include optic nerve head dysplasia, microcornea, and Rathke's cleft cyst. Some patients manifest pituitary dysfunction. |
