Genes affected
KAT14 (HGNC:15904): (lysine acetyltransferase 14) CSRP2 is a protein containing two LIM domains, which are double zinc finger motifs found in proteins of diverse function. CSRP2 and some related proteins are thought to act as protein adapters, bridging two or more proteins to form a larger protein complex. The protein encoded by this gene binds to one of the LIM domains of CSRP2 and contains an acetyltransferase domain. Although the encoded protein has been detected in the cytoplasm, it is predominantly a nuclear protein. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jun 2011]
PET117 (HGNC:40045): (PET117 cytochrome c oxidase chaperone) Predicted to be involved in mitochondrial cytochrome c oxidase assembly. Located in mitochondrion. Implicated in cytochrome-c oxidase deficiency disease. [provided by Alliance of Genome Resources, Apr 2022]

Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.157C>T (p.R53C) alteration is located in exon 2 (coding exon 2) of the PET117 gene. This alteration results from a C to T substitution at nucleotide position 157, causing the arginine (R) at amino acid position 53 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
