Genes affected

SUPT20H (HGNC:20596): (SPT20 homolog, SAGA complex component) Predicted to enable transcription coregulator activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to act upstream of or within positive regulation of gluconeogenesis and positive regulation of transcription by RNA polymerase II. Part of SAGA-type complex.

EXOSC8 (HGNC:17035): (exosome component 8) This gene encodes a 3'-5' exoribonuclease that specifically interacts with mRNAs containing AU-rich elements. The encoded protein is part of the exosome complex that is important for the degradation of numerous RNA species. A pseudogene of this gene is found on chromosome 6. [provided by RefSeq, Mar 2009]

The c.1516C>T (p.R506W) alteration is located in exon 19 (coding exon 18) of the SUPT20H gene. This alteration results from a C to T substitution at nucleotide position 1516, causing the arginine (R) at amino acid position 506 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
