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]

Ambry Genetics

Nov 10, 2023

The c.592C>T (p.R198C) alteration is located in exon 5 (coding exon 4) of the DCAKD gene. This alteration results from a C to T substitution at nucleotide position 592, causing the arginine (R) at amino acid position 198 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
