Ivone Leong Added comment: Comment on mode of inheritance: Change MOI from "X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males)" to "X-LINKED: hemizygous mutation in males, biallelic mutations in females" to reflect the MOI that is given to this gene on the "Possible mitochondrial disorder - nuclear genes" (code: 539, v1.12).
Ivone Leong Mode of inheritance for gene: ABCB7 was changed from X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males) to X-LINKED: hemizygous mutation in males, biallelic mutations in females
