Proteinuric renal disease v2.67 AMN Eleanor Williams Phenotypes for gene: AMN were changed from Megaloblastic anemia-1, Norwegian type, 261100; (originally on the Imerslund-Grasbeck syndrome gene panel) to Megaloblastic anemia-1, Norwegian type, OMIM:261100
Proteinuric renal disease v2.66 AMN Eleanor Williams Tag for-review was removed from gene: AMN.
Proteinuric renal disease v2.66 AMN Eleanor Williams commented on gene: AMN: The rating of this gene has been updated following NHS Genomic Medicine Service approval. The reviewers note that a homozygous splice variant in patient with Imerslund-Grasbeck syndrome has been reported.
Proteinuric renal disease v2.65 AMN Eleanor Williams Source Expert Review Green was added to AMN.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Proteinuric renal disease v2.27 AMN Catherine Snow Classified gene: AMN as Amber List (moderate evidence)
Proteinuric renal disease v2.27 AMN Catherine Snow Added comment: Comment on list classification: Changed rating to Amber to reflect NHS signed-off rating, will be examined at next panel review.
Proteinuric renal disease v2.27 AMN Catherine Snow Gene: amn has been classified as Amber List (Moderate Evidence).
Proteinuric renal disease v2.26 AMN Eleanor Williams Tag for-review tag was added to gene: AMN.
Proteinuric renal disease v2.16 AMN Eleanor Williams Classified gene: AMN as Green List (high evidence)
Proteinuric renal disease v2.16 AMN Eleanor Williams Added comment: Comment on list classification: Changing rating from amber to green following expert review stating that proteinuria is a well known presenting feature of IMERSLUND-GRASBECK SYNDROME. At least 3 cases with variants in AMN and proteinuria are reported in the literature.
Proteinuric renal disease v2.16 AMN Eleanor Williams Gene: amn has been classified as Green List (High Evidence).
Proteinuric renal disease v2.15 AMN Eleanor Williams commented on gene: AMN: Associated with Megaloblastic anemia-1, Norwegian type #261100 (AR) in OMIM which is also known as IMERSLUND-GRASBECK SYNDROME (IGS).

PMID: 30691194 - Pacitto et al 2019 - describe a case of IGS with urinary tract infection and mild but persistent proteinuria at onset in an 11-month-old female child. The patient was found to be compound heterzygous for a novel intronic variant c.513+5G>A thought to affect a donor splice site, and the known pathogenetic variant c.1006+34_1007-31del. Parents each had one of the variants.

PMID: 26040326 - Montgomery et al 2015 - 2 half sisters with IGS and compound heterzygous variants in AMN are reported (c.35delA, p.Gln12Argfs*5) and (c.206 T > A, p.Met69Lys). Both presented with sub-nephrotic range proteinuria.

PMID: 22631584 - Densupsoontorn et al 2012 - report a Thai boy with IGS in whom a deleterious mutation in AMN was confirmed (homozygous c.663G>A; W221X). Persistent proteinuria was reported.

Note - not all patients are described as presenting with proteinuria e.g. PMID: 14593474 (Molecular cause of IGS unknown in this case).
Proteinuric renal disease v2.0 AMN Zornitza Stark reviewed gene: AMN: Rating: GREEN; Mode of pathogenicity: None; Publications: 30691194, 26040326; Phenotypes: ; Mode of inheritance: BIALLELIC, autosomal or pseudoautosomal; Current diagnostic: yes
Proteinuric renal disease v1.217 AMN Eleanor Williams Classified gene: AMN as Amber List (moderate evidence)
Proteinuric renal disease v1.217 AMN Eleanor Williams Added comment: Comment on list classification: Changing rating from green to amber until a review of the degree of proteinuria in patients with Imerslund-Grasbeck syndrome has been done.
Proteinuric renal disease v1.217 AMN Eleanor Williams Gene: amn has been classified as Amber List (Moderate Evidence).
Proteinuric renal disease v1.134 AMN Eleanor Williams Publications for gene: AMN were set to 12590260
Proteinuric renal disease v1.16 AMN Eleanor Williams reviewed gene: AMN: Rating: AMBER; Mode of pathogenicity: ; Publications: PMID: 26040326; Phenotypes: Megaloblastic anemia-1, Norwegian type #261100; Mode of inheritance: BIALLELIC, autosomal or pseudoautosomal
Proteinuric renal disease v1.15 AMN Eleanor Williams Source NHS GMS was added to AMN.
Rating Changed from Green List (high evidence) to Green List (high evidence)
