Genes affected

MAP4K1 (HGNC:6863): (mitogen-activated protein kinase kinase kinase kinase 1) Enables ATP binding activity and MAP kinase kinase kinase kinase activity. Involved in several processes, including JNK cascade; cellular response to phorbol 13-acetate 12-myristate; and protein phosphorylation. Located in membrane. [provided by Alliance of Genome Resources, Apr 2022]

MAP4K1 links:

RYR1 (HGNC:10483): (ryanodine receptor 1) This gene encodes a ryanodine receptor found in skeletal muscle. The encoded protein functions as a calcium release channel in the sarcoplasmic reticulum but also serves to connect the sarcoplasmic reticulum and transverse tubule. Mutations in this gene are associated with malignant hyperthermia susceptibility, central core disease, and minicore myopathy with external ophthalmoplegia. Alternatively spliced transcripts encoding different isoforms have been described. [provided by RefSeq, Jul 2008]

The c.2366C>A (p.T789N) alteration is located in exon 30 (coding exon 30) of the MAP4K1 gene. This alteration results from a C to A substitution at nucleotide position 2366, causing the threonine (T) at amino acid position 789 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
