Deletions and mutations in this gene were found in patients with intellectual disability. This gene is expressed at a high level in post-natal brain structures involved in the hippocampal memory system, which suggests a specialized role in the physiological processes underlying memory and learning abilities, and plays a role in synapse formation and stabilization.

IL1R8, IL1RAPL, MRX10, MRX21, MRX34, OPHN4, TIGIRR-2. The protein encoded by this gene is a member of the interleukin 1 receptor family and is similar to the interleukin 1 accessory proteins. Deletions and mutations in this gene were found in patients with intellectual disability. Deletions and mutations in this gene were found in patients with mental retardation. This gene is expressed at a high level in post-natal brain structures involved in the hippocampal memory system, which suggests a specialized role in the physiological processes underlying memory and learning abilities.

IL1RAPL1 (interleukin‐1 receptor accessory protein‐like 1) located at Xp21.3‐22.1 has repeatedly been shown to be deleted in patients with a contiguous gene syndrome also affecting neighboring genes, in particular DMD (dystrophin), DAX‐1 (NR0B1, nuclear receptor subfamily 0, group B, member 1), and GK (glycerol kinase).

In this report, we present the results of the molecular analyses and clinical Startle epilepsy is a type of reflex epilepsy in which the seizures are mainly precipitated by unexpected sensory stimuli. IL1RAPL1 gene product.

2011-09-21 · In a boy with MRX21 , Piton et al. (2008) identified a 730-kb deletion in the IL1RAPL1 gene, resulting in the deletion of exons 3 through 7 and causing premature termination.

Eur J Med Genet, 2012 Jan. PMID 21933724 IL1RAPL1 may also be deleted in families with a contiguous gene deletion syndrome that includes MR, adrenal hypoplasia, Duchenne muscular dystrophy, and glycerol kinase deficiency. For patients with suspected XLMR 21, sequence analysis is recommended as the first step in mutation identification. For patients in whom mutations 2014-08-01 · It is selectively expressed in the brain and plays a crucial role in cognitive development.11, 12 The IL1RAPL1 gene is located on Xp21.2-p21.3, a deletion and/or mutation-prone region. 13 Mutations of this gene have been associated with cognitive impairments ranging from nonsyndromic X-linked mental retardation to autistic spectrum disorders. 4 IL1RAPL1 affects the release of neurotransmitters through calcium-dependent exocytosis and is involved in synaptic formation and IL-1 receptor accessory protein-like 1 (IL1RAPL1) is the product of an X-linked gene responsible for a nonsyndromic form of ID. The IL1RAPL1 gene is also associated with autism spectrum disorders 2011-09-21 · In a boy with MRX21 , Piton et al.

Deletions and mutations in this gene were found in patients with intellectual disability. Deletions and mutations in this gene were found in patients with mental retardation. This gene is expressed at a high level in post-natal brain structures involved in the hippocampal memory system, which suggests a specialized role in the physiological processes underlying memory and learning abilities. [provided by RefSeq, Jul 2008]. To the Editor: Defects in a number of genes distributed on the human X chromosome have been associated with mental retardation (MR) and developmental delay (DD) (1–3). We have evaluated a 7-yearold boy with global DD, autism, facial dysmorphism and a pericentromeric inversion of the X chromosome. The patient was a full-term infant born to a 25-year-old female with mild MR (Fig.

The protein encoded by this gene is a member of the interleukin 1 receptor family and is similar to the interleukin 1 accessory proteins. Diseases such as Mental Retardation, X-Linked 21, and Non-Syndromic X-Linked Intellectual Disability are associated with IL1RAPL1. In a systematic sequencing screen of synaptic genes on the X chromosome, we have identified an autistic female without mental retardation (MR) who carries a de novo frameshift Ile367SerfsX6 mutation in Interleukin-1 Receptor Accessory Protein-Like 1 (IL1RAPL1), a gene implicated in calcium-regulated vesicle release and dendrite differentiation. 2021-04-07 · The coexistence of startle epilepsy and IL1RAPL1 gene deletion in this child may not be coincidental and suggests a possible involvement of IL1RAPL1 in the dysregulation of excitatory synapses and the pathogenesis of startle epilepsy.

The genomic deletion observed in patient II-3 thus results in the deletion of exons 3 to 7 of the IL1RAPL1 gene ( Figure 5e). This deletion is predicted to cause a frameshift at alanine 28 with a premature stop codon 15 codons downstream (Ala28GlufsX15), thus truncating the majority of the IL1RAPL1 … Reports Added [Disruption of the IL1RAPL1 gene associated with a pericentromeric inversion of the X chromosome in a patient with mental retardation and autism.2007] [Mutations in the calcium-related gene IL1RAPL1 are associated with autism.2008] [Functional impact of global rare copy number variation in autism spectrum disorders.2010] [Direct measure of the de novo mutation rate in autism and Deletions and mutations in this gene were found in patients with intellectual disability.

Conclusions: The IL1RAPL1 gene is located on Xp21.2-p21.3 and codes a synaptic adhesion protein involved in neuronal differentiation and synapse localization, stabilization, and maturation. The coexistence of startle epilepsy and IL1RAPL1 gene deletion in this child may not be coincidental and suggests a possible involvement of IL1RAPL1 in the
