Description

The ANK1 c.2803C>T; p.Arg935Ter variant is reported in the literature in multiple individuals with spherocytosis or hemolytic anemia (Choi 2019, Del Orbe Barreto 2016, Gao 2018, Muramatsu 2017, Tole 2020, Wang 2018). This variant is also reported in ClinVar (Variation ID: 1330761). This variant is absent from the Genome Aggregation Database, indicating it is not a common polymorphism. This variant induces an early termination codon and is predicted to result in a truncated protein or mRNA subject to nonsense-mediated decay. Based on available information, this variant is considered to be pathogenic. REFERENCES Choi HS et al.
