Genes affected

PANK4 (HGNC:19366): (pantothenate kinase 4 (inactive)) This gene encodes a protein belonging to the pantothenate kinase family. Pantothenate kinase is a key regulatory enzyme in the biosynthesis of coenzyme A (CoA) in bacteria and mammalian cells. It catalyzes the first committed step in the universal biosynthetic pathway leading to CoA and is itself subject to regulation through feedback inhibition by CoA. This family member is most abundant in muscle but is expressed in all tissues. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.1805C>G (p.S602C) alteration is located in exon 15 (coding exon 15) of the PANK4 gene. This alteration results from a C to G substitution at nucleotide position 1805, causing the serine (S) at amino acid position 602 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
