Introduction to Microphthalmia with Limb Anomalies
Microphthalmia with limb anomalies (MLA) is a rare autosomal-recessive disease characterized by ocular disorders and limb anomalies. It is caused by mutations in the SMOC1 gene.
Microphthalmia with limb anomalies (MLA) is a rare autosomal-recessive disease characterized by ocular and limb abnormalities. The condition is caused by biallelic pathogenic variants in the SMOC1 gene٫ leading to features like microphthalmia or anophthalmia and limb anomalies such as synostosis٫ syndactyly٫ and oligodactyly. Developmental delays٫ intellectual disabilities٫ and other associated anomalies contribute to the complexity of MLA.
Genetic Basis of Microphthalmia with Limb Anomalies
Microphthalmia with limb anomalies (MLA) is a rare genetic disorder characterized by ocular and limb abnormalities caused by mutations in the SMOC1 gene.
SMOC1 Gene Mutations
Studies have shown that biallelic pathogenic variants in the SMOC1 gene are responsible for causing Microphthalmia with Limb Anomalies. These mutations have been identified in various affected individuals and families٫ highlighting the critical role of the SMOC1 gene in the development of this rare genetic disorder.
Hereditary vs. Random Genetic Mutations
Microphthalmia with limb anomalies can result from hereditary genetic mutations passed down from parents or random mutations occurring during cell division. These mutations often occur in the SMOC1 gene٫ leading to the manifestation of the rare genetic disorder. Understanding the underlying mechanisms of both hereditary and random genetic mutations is crucial in diagnosing and managing this condition effectively.
Overview of the Disease
Microphthalmia with limb anomalies (MLA) is a rare autosomal-recessive disease characterized by ocular and limb abnormalities. The condition is caused by biallelic pathogenic variants in the SMOC1 gene, leading to features like microphthalmia or anophthalmia and limb anomalies such as synostosis, syndactyly, and oligodactyly. Developmental delays, intellectual disabilities, and other associated anomalies contribute to the complexity of MLA.
Ocular Features
Patients with Microphthalmia with Limb Anomalies (MLA) often present with microphthalmia or anophthalmia, which may manifest unilaterally or bilaterally. Additionally, they may exhibit severe vision impairment. Associated limb anomalies commonly include synostosis of the fourth and fifth metacarpals, a short fifth finger, and only four toes on each foot bilaterally. Developmental milestones are often delayed, and intellectual disabilities range from moderate to severe in affected individuals.
Limb Anomalies and Associated Conditions
Patients with Microphthalmia with Limb Anomalies (MLA) commonly exhibit limb anomalies such as synostosis of the fourth and fifth metacarpals, a short fifth finger, and only four toes on each foot bilaterally.
