Genes affected
SIN3A (HGNC:19353): (SIN3 transcription regulator family member A) The protein encoded by this gene is a transcriptional regulatory protein. It contains paired amphipathic helix (PAH) domains, which are important for protein-protein interactions and may mediate repression by the Mad-Max complex. [provided by RefSeq, Jul 2008]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 29, 2023The c.3639G>C (p.W1213C) alteration is located in exon 21 (coding exon 20) of the SIN3A gene. This alteration results from a G to C substitution at nucleotide position 3639, causing the tryptophan (W) at amino acid position 1213 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
