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. [provided by Alliance of Genome Resources, Apr 2022]
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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 23, 2021The c.1464C>A (p.S488R) alteration is located in exon 19 (coding exon 18) of the SUPT20H gene. This alteration results from a C to A substitution at nucleotide position 1464, causing the serine (S) at amino acid position 488 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
