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 was made for transcript

Our verdict: Benign. The variant received -17 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.006172359).

BP6

Variant 20-32436601-G-A is Benign according to our data. Variant chr20-32436601-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 133597.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population afr. GnomAdExome4 allele frequency = 0.000125 (182/1461850) while in subpopulation AFR AF = 0.00227 (76/33480). AF 95% confidence interval is 0.00186. There are 1 homozygotes in GnomAdExome4. There are 86 alleles in the male GnomAdExome4 subpopulation. Median coverage is 41. This position passed quality control check.

BS2

High AC in GnomAd4 at 85 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
