Genes affected
SUPT6H (HGNC:11470): (SPT6 homolog, histone chaperone and transcription elongation factor) Enables histone binding activity. Involved in negative regulation of histone H3-K27 methylation and positive regulation of transcription elongation from RNA polymerase II promoter. Predicted to be located in nucleoplasm. Predicted to be part of transcription elongation factor complex. Predicted to be active in transcriptionally active chromatin. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 17, 2022The c.785G>A (p.R262H) alteration is located in exon 7 (coding exon 6) of the SUPT6H gene. This alteration results from a G to A substitution at nucleotide position 785, causing the arginine (R) at amino acid position 262 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
