Microphthalmia with limb anomalies (MLA), also known as Waardenburg anophthalmia syndrome or ophthalmoacromelic syndrome, is a rare autosomal-recessive disorder, presenting with unilateral or bilateral microphthalmia, clinical anophthalmia, and limb abnormalities such as syndactyly, brachydactyly, camptodactyly, synostosis, hip dislocation, absence, or hypoplasia of fibula, and bowed tibia. In addition, other organs may be affected (long-bone hypoplasia; renal, venous, and vertebral anomalies). It has been shown that mutations in SMOC1 gene cause this disorder.
