chrX-28789425-G-A

Variant summary

Our verdict is Likely benign. Variant got -1 ACMG points: 4P and 5B. PP3_StrongBP6BS2

The NM_014271.4(IL1RAPL1):c.82G>A(p.Ala28Thr) variant causes a missense, splice region change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000145 in 1,175,560 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 8 hemizygotes in GnomAD. In-silico tool predicts a benign outcome for this variant. 2/3 splice prediction tools predicting alterations to normal splicing. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. A28A) has been classified as Likely benign.

Genes affected

IL1RAPL1 (HGNC:5996): (interleukin 1 receptor accessory protein like 1) The protein encoded by this gene is a member of the interleukin 1 receptor family and is similar to the interleukin 1 accessory proteins. This protein has an N-terminal signal peptide, three extracellular immunoglobulin Ig-like domains, a transmembrane domain, an intracellular Toll/IL-1R domain, and a long C-terminal tail which interacts with multiple signalling molecules. This gene is located at a region on chromosome X that is associated with a non-syndromic form of X-linked intellectual disability. 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.
