Primary immunodeficiency or monogenic inflammatory bowel disease v4.175 ANKZF1 Achchuthan Shanmugasundram Classified gene: ANKZF1 as Amber List (moderate evidence)
Primary immunodeficiency or monogenic inflammatory bowel disease v4.175 ANKZF1 Achchuthan Shanmugasundram Added comment: Comment on list classification: AS there is sufficient evidence for the association of monoallelic variants with infantile-onset inflammatory bowel disease, this gene can be promoted to green rating in the next GMS review.
Primary immunodeficiency or monogenic inflammatory bowel disease v4.175 ANKZF1 Achchuthan Shanmugasundram Gene: ankzf1 has been classified as Amber List (Moderate Evidence).
Primary immunodeficiency or monogenic inflammatory bowel disease v4.174 ANKZF1 Achchuthan Shanmugasundram changed review comment from: Comment on mode of inheritance: There are three unrelated cases reported with monoallelic ANKZF1 variants and infantile-onset inflammatory bowel disease. However, there are only two unrelated cases reported with biallelic variants, of which one has homozygous variant and other has compound heterozygous variants. The homozygous variant (p.Arg585Gln) is very common in gnomAD. Functional studies show that R585Q variant causes reduced ANKZF1 mRNA and protein expression and leads to reduced stress-induced mitochondrial translocation.

The MOI should therefore be set as "MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted" with the current evidence. In addition, 'watchlist_MOI' tag has been added to review any new evidence in support of the association of biallelic variants to inflammatory bowel disease.; to: Comment on mode of inheritance: There are three unrelated cases reported with monoallelic ANKZF1 variants and infantile-onset inflammatory bowel disease.

Added comment: PMID: 28302725 (2017) identified two infantile-onset IBD patients with biallelic ANKZF1 variants + some functional work:
One homozygous for R585Q - although this variant is very common in gnomAD
One compound heterozygous for E152K and V32_Q87del
Also two patients with one heterozygous variants

PMID: 36857589 (2023) also identified a de novo variant (p.Leu415Val) in a young patient with IBD
