Mendeliome v1.2844 MAP4K1 Zornitza Stark Classified gene: MAP4K1 as Green List (high evidence)
Mendeliome v1.2844 MAP4K1 Zornitza Stark Gene: map4k1 has been classified as Green List (High Evidence).
Mendeliome v1.2843 MAP4K1 Zornitza Stark gene: MAP4K1 was added
gene: MAP4K1 was added to Mendeliome. Sources: Expert Review
Mode of inheritance for gene: MAP4K1 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Publications for gene: MAP4K1 were set to 40716650
Phenotypes for gene: MAP4K1 were set to Inborn error of immunity, MONDO:0003778, MAP4K1-related
Review for gene: MAP4K1 was set to GREEN
Added comment: Heterozygous MAP4K1 loss-of-function variants were identified in two kindreds presenting with diverse immune dysregulatory symptoms, including recurrent fevers, inflammatory arthritis, EBV-related complications, and nephritis. Functional analysis of primary patient T cells, transcriptomics, and CRISPR-Cas9 editing demonstrated that HPK1 deficiency heightened T cell activation and inflammatory cytokine production. Penetrance was incomplete.

One of the families was multiplex (8 affected individuals) and the other had single individual affected, extensive functional data. Borderline Amber/Green.
