Loss of the BMP antagonist, SMOC-1, causes Ophthalmo-acromelic (Waardenburg Anophthalmia) syndrome in humans and mice.

Ophthalmo-acromelic syndrome (OAS), also known as Waardenburg Anophthalmia syndrome, is defined by the combination of eye malformations, most commonly bilateral anophthalmia, with post-axial oligosyndactyly. Homozygosity mapping and subsequent targeted mutation analysis of a locus on 14q24.2 identified homozygous mutations in SMOC1 (SPARC-related modular calcium binding 1) in eight unrelated families.

BMP4 loss-of-function mutations in developmental eye disorders including SHORT syndrome.

BMP4 loss-of-function mutations and deletions have been shown to be associated with ocular, digital, and brain anomalies, but due to the paucity of these reports, the full phenotypic spectrum of human BMP4 mutations is not clear. We screened 133 patients with a variety of ocular disorders for BMP4 coding region mutations or genomic deletions. BMP4 deletions were detected in two patients: a patient affected with SHORT syndrome and a patient with anterior segment anomalies along with craniofacial dysmorphism and cognitive impairment.

Clinical report of microphthalmia and optic nerve coloboma associated with a de novo microdeletion of chromosome 16p11.2.

Anophthalmia and microphthalmia are etiologically and clinically heterogeneous. We present a 13-year-old boy with microphthalmia and multiple anomalies who was evaluated as part of our research into the etiology of microphthalmia. His clinical features included left microphthalmia, persistent hyperplastic primary vitreous and posterior coloboma, right posterior pole coloboma, pectus excavatum, mild hypotonia, mild delays in speech and motor development, and an anxiety disorder with social difficulties.

Association of a de novo 16q copy number variant with a phenotype that overlaps with Lenz microphthalmia and Townes-Brocks syndromes.

Background: Anophthalmia and microphthalmia are etiologically and clinically heterogeneous. Lenz microphthalmia is a syndromic form that is typically inherited in an X-linked pattern, though the causative gene mutation is unknown. Townes-Brocks syndrome manifests thumb anomalies, imperforate anus, and ear anomalies.

Mutations in the human RAX homeobox gene in a patient with anophthalmia and sclerocornea.

Anophthalmia and microphthalmia are among the most common ocular birth defects and a significant cause of congenital blindness. The etiology of anophthalmia and microphthalmia is diverse, with multiple genetic mutations associated with each of these conditions, along with potential environmental causes. Based on findings that mutations in the Rx/Rax homeobox genes in mice and fish lead to defects in retinal development and result in animal models of anophthalmia, we screened 75 individuals with anophthalmia and/or microphthalmia for mutations in the human RAX gene.
