Normal function

ALPK1 encodes a Ser/Thr alpha-kinase that detects bacterial pathogen-associated molecular pattern metabolites (PAMPs) to initiate an innate immune response involving pro-inflammatory NF-kappaB signaling (PMID: 28877472, 28222186, 30111836). It has also been implicated in apical protein transport by mediating phosphorylation of unconventional myosin MYO1A (PMID: 15883161), as well as in ciliogenesis (PMID: 30967659).

Dysfunction and disease

Heterozygous GOF mutations in ALPK1 are associated with ROSAH (Retinal dystrophy, optic nerve edema, splenomegaly, anhidrosis, and migraine headache) syndrome [OMIM: 614979], an AD disorder featuring childhood-onset reduced vision associated with papilledema, low-grade ocular inflammation unresponsive to immunosuppression and progressive deterioration of visual acuity. Patients also show anhidrosis, splenomegaly, chronic mild pancytopenia that may be exacerbated during infections, migraine-like headaches often accompanied by episodic fevers with back and joint pains, dental and/or nail issues, and variable renal impairment (PMID: 22307799, 30967659, 31939038). Peripheral smears frequently show leukopenia with reactive lymphocytosis, while bone marrow is normocellular with trilineage hematopoiesis and relative erythroid hyperplasia. Immunophenotyping performed on 2 Chinese patients found elevated inflammatory markers and serum TNF-alpha levels, as well as reduced CD19+ B cell counts and low IgM in one patient (PMID: 31939038).
