Genes affected
HBB (HGNC:4827): (hemoglobin subunit beta) The alpha (HBA) and beta (HBB) loci determine the structure of the 2 types of polypeptide chains in adult hemoglobin, Hb A. The normal adult hemoglobin tetramer consists of two alpha chains and two beta chains. Mutant beta globin causes sickle cell anemia. Absence of beta chain causes beta-zero-thalassemia. Reduced amounts of detectable beta globin causes beta-plus-thalassemia. The order of the genes in the beta-globin cluster is 5'-epsilon -- gamma-G -- gamma-A -- delta -- beta--3'.

Classification made for transcript
Verdict is Uncertain_significance. Variant got 2 ACMG points.
PM2
?
Very rare variant in population databases, with high coverage;
PP5
?
Variant 11-5227096-C-A is Pathogenic according to our data. Variant chr11-5227096-C-A is described in ClinVar as [Pathogenic]. Clinvar id is 869256.Status of the report is no_assertion_criteria_provided, 0 stars.
BP4
?
Computational evidence support a benign effect (BayesDel_noAF=-0.5). . Strength limited to SUPPORTING due to the PP5.
