Genes affected

SUPT16H (HGNC:11465): (SPT16 homolog, facilitates chromatin remodeling subunit) Transcription of protein-coding genes can be reconstituted on naked DNA with only the general transcription factors and RNA polymerase II. However, this minimal system cannot transcribe DNA packaged into chromatin, indicating that accessory factors may facilitate access to DNA. One such factor, FACT (facilitates chromatin transcription), interacts specifically with histones H2A/H2B to effect nucleosome disassembly and transcription elongation. FACT is composed of an 80 kDa subunit and a 140 kDa subunit; this gene encodes the 140 kDa subunit. [provided by RefSeq, Feb 2009]

The SUPT16H c.3092C>T (p.Ser1031Phe) variant, to our knowledge, has not been reported in the medical literature and is only observed on 1/249,996 alleles in the general population (gnomAD v.2.1.1), indicating it is not a common variant. This variant occurs in a disordered domain that wraps around the DNA-binding surface of H2A-H2B (Liu Y et al., PMID: 31775157) and changes a polar serine to a nonpolar phenylalanine, but computational predictors suggest that the variant does not impact SUPT16H function. Due to limited information, and based on ACMG/AMP guidelines for variant interpretation (Richards S et al., PMID: 25741868), the clinical significance of this variant is uncertain at this time. -
