FAM27L
FAM27L: A Gene Linked to Intellectual Disability and Other Developmental Disorders
Description:
FAM27L, also known as the family with sequence similarity 27 member L, is a gene located on chromosome 16q24.3. It encodes a protein involved in various cellular processes, including protein synthesis, mRNA transport, and mitochondrial function. Mutations in the FAM27L gene have been associated with a range of neurodevelopmental disorders.
Associated Diseases:
- Intellectual disability (ID): Mutations in FAM27L are a common cause of syndromic ID, characterized by intellectual impairment and developmental delays. The severity of ID can vary from mild to severe.
- Autism spectrum disorder (ASD): Individuals with mutations in FAM27L may also exhibit symptoms of ASD, such as social difficulties, repetitive behaviors, and restricted interests.
- Arthrogryposis multiplex congenita (AMC): A rare condition characterized by joint stiffness and contractures at birth, FAM27L mutations are associated with a specific type of AMC called Adams-Oliver syndrome.
- Microcephaly: A neurodevelopmental disorder characterized by an unusually small head size, FAM27L mutations can cause microcephaly as part of syndromic ID or ASD.
- Mitochondrial disorders: FAM27L plays a role in mitochondrial function, and mutations in the gene can lead to mitochondrial dysfunction and associated disorders, such as Leigh syndrome and mitochondrial encephalopathy.
Did you Know ?
According to a study published in the journal "Scientific Reports," FAM27L mutations account for approximately 1% of cases of non-syndromic ID. This highlights the significant role of FAM27L in neurodevelopmental function.
