Genes affected

DCAKD (HGNC:26238): (dephospho-CoA kinase domain containing) Predicted to enable dephospho-CoA kinase activity. Predicted to be involved in coenzyme A biosynthetic process. Located in membrane. [provided by Alliance of Genome Resources, Apr 2022]

DCAKD links:

NMT1 (HGNC:7857): (N-myristoyltransferase 1) Myristate, a rare 14-carbon saturated fatty acid, is cotranslationally attached by an amide linkage to the N-terminal glycine residue of cellular and viral proteins with diverse functions. N-myristoyltransferase (NMT; EC 2.3.1.97) catalyzes the transfer of myristate from CoA to proteins. N-myristoylation appears to be irreversible and is required for full expression of the biologic activities of several N-myristoylated proteins, including the alpha subunit of the signal-transducing guanine nucleotide-binding protein (G protein) GO (GNAO1; MIM 139311) (Duronio et al., 1992 [PubMed 1570339]).[supplied by OMIM, Nov 2008]

Dec 15, 2023

The c.337G>A (p.D113N) alteration is located in exon 4 (coding exon 3) of the DCAKD gene. This alteration results from a G to A substitution at nucleotide position 337, causing the aspartic acid (D) at amino acid position 113 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
