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 Benign. Variant got -11 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.004910469).

BP6

Variant 20-32436215-G-C is Benign according to our data. Variant chr20-32436215-G-C is described in ClinVar as [Likely_benign]. Clinvar id is 133596.Status of the report is criteria_provided_single_submitter, 1 stars.

BS1

Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.000176 (258/1461884) while in subpopulation SAS AF= 0.00254 (219/86258). AF 95% confidence interval is 0.00226. There are 4 homozygotes in gnomad4_exome. There are 191 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck.

BS2

High AC in GnomAd4 at 15 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
