Genes affected

ASXL1 (HGNC:18318): (ASXL transcriptional regulator 1) This gene is similar to the Drosophila additional sex combs gene, which encodes a chromatin-binding protein required for normal determination of segment identity in the developing embryo. The protein is a member of the Polycomb group of proteins, which are necessary for the maintenance of stable repression of homeotic and other loci. The protein is thought to disrupt chromatin in localized areas, enhancing transcription of certain genes while repressing the transcription of other genes. The protein encoded by this gene functions as a ligand-dependent co-activator for retinoic acid receptor in cooperation with nuclear receptor coactivator 1. Mutations in this gene are associated with myelodysplastic syndromes and chronic myelomonocytic leukemia. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2009]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 0 ACMG points.

PM4

Nonframeshift variant in NON repetitive region in NM_015338.6. Strenght limited to Supporting due to length of the change: 1aa.

BS2

High AC in GnomAdExome4 at 37 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

ClinVar contains an entry for this variant (Variation ID: 548554). This variant, c.4112_4114del, results in the deletion of 1 amino acid(s) of the ASXL1 protein (p.Lys1371del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs752856195, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with ASXL1-related conditions. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
