Genes affected

IL33 (HGNC:16028): (interleukin 33) The protein encoded by this gene is a cytokine that binds to the IL1RL1/ST2 receptor. The encoded protein is involved in the maturation of Th2 cells and the activation of mast cells, basophils, eosinophils and natural killer cells. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2015]

LOC107987046 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.002708286).
• BP6: Variant 9-6256144-C-G is Benign according to our data. Variant chr9-6256144-C-G is described in ClinVar as [Benign]. Clinvar id is 776409.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0105 (1595/152126) while in subpopulation AFR AF= 0.0364 (1512/41506). AF 95% confidence interval is 0.0349. There are 24 homozygotes in gnomad4. There are 740 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 24 AR gene
