Rare anaemia

Gene: KLF1

The mode of inheritance of this gene has been updated to 'BOTH monoallelic and biallelic (but BIALLELIC mutations cause a more SEVERE disease form), autosomal or pseudoautosomal' following NHS Genomic Medicine Service approval.

Created: 1 Feb 2023, 9:06 a.m. | Last Modified: 1 Feb 2023, 9:06 a.m.

Panel Version: 2.3

Comment on mode of inheritance: MOI should be updated from 'Monoallelic' only to 'Both mono- and biallelic, (biallelic more severe)'.

The expanded MOI is based on compound heterozygous cases in PMID:24443441; 25724378; 27282573; 28361594; 28369821. Heterozygous carrier parents may display features of beta thalassemia.
