Bone Marrow Failure v1.0 AK2 Zornitza Stark edited their review of gene: AK2: Changed publications: 19043416, 19043417
Bone Marrow Failure v1.0 AK2 Zornitza Stark changed review comment from: Well established gene-disease association.; to: Well established gene-disease association.

PMID: 19043417 (2009). 6 affected individuals from 5 unrelated families (3 of the families showed evidence of consanguinity). Homozygous (5 individuals) and compound heterozygous (1 individual) variants in the AK2 gene. Variants included missense, deletion and inframe indel, resulting in protein LoF. Available parents were sequenced and found heterozygous for the variants, supporting bi-allelic inheritance.

PMID: 19043416 (2009). 7 affected individuals from 6 unrelated families (2 separate consanguineous & 4 non-consanguineous families). Homozygous and compound heterozygous variants detected (missense, deletion, inframe indel), resulting in protein LoF. Reticular dysgenesis phenotype including Leukopenia, lymphopenia and agranulocytosis in all affected individuals and sensorineural deafness in 7 individuals.
