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]

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. -
