Genes affected
SNAPC4 (HGNC:11137): (small nuclear RNA activating complex polypeptide 4) This gene encodes the largest subunit of the small nuclear RNA-activating protein (SNAP) complex. The encoded protein contains a Myb DNA-binding domain, and is essential for RNA polymerase II and III polymerase transcription from small nuclear RNA promoters. A mutation in this gene is associated with ankylosing spondylitis. [provided by RefSeq, Jul 2016]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 22, 2022The c.334C>T (p.R112W) alteration is located in exon 3 (coding exon 3) of the SNAPC4 gene. This alteration results from a C to T substitution at nucleotide position 334, causing the arginine (R) at amino acid position 112 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
