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 30, 2021The c.2159T>G (p.F720C) alteration is located in exon 25 (coding exon 24) of the SUPT20H gene. This alteration results from a T to G substitution at nucleotide position 2159, causing the phenylalanine (F) at amino acid position 720 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
