Pathological Phenotypes: 1

Microphthalmia with limb anomalies
OMIM: #206920

Microphthalmia with limb anomalies is caused by homozygous mutations in the SMOC1 gene. Distinctive features are unilateral or bilateral anophthalmia with limb anomalies. Intellectual disabilities is also a common feature. The most common limb anomalies are toe syndactyly, oligodactyly, metacarpal synostosis, camptodactyly and finger syndactyly. Less commonly patients can show also other types of abnormalities like bowed tibia, synostosis of carpals/tarsals, sandal gap and finger clinodactyly.
