Rare anaemia

Gene: ABCB7

The mode of inheritance of this gene has been updated to 'X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males)' 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

MOI should be changed from "X-LINKED: hemizygous mutation in males, biallelic mutations in females" to "X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males)" as some carrier females have ring sideroblasts, dimorphic peripheral bloode smear, hypochromic and microcytic erythrocytes but no evidence of ataxia.
