Genes affected

PSIP1 (HGNC:9527): (PC4 and SRSF1 interacting protein 1) Enables DNA-binding transcription factor binding activity; chromatin binding activity; and transcription coactivator activity. Involved in mRNA 5'-splice site recognition and positive regulation of transcription by RNA polymerase II. Located in heterochromatin; nuclear periphery; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

PSIP1 links:

SNAPC3 (HGNC:11136): (small nuclear RNA activating complex polypeptide 3) Predicted to enable RNA polymerase III type 3 promoter sequence-specific DNA binding activity and bent DNA binding activity. Predicted to contribute to RNA polymerase II cis-regulatory region sequence-specific DNA binding activity and core promoter sequence-specific DNA binding activity. Predicted to be involved in snRNA transcription by RNA polymerase II and snRNA transcription by RNA polymerase III. Located in nuclear body and nucleolus.

The c.1436A>G (p.N479S) alteration is located in exon 15 (coding exon 14) of the PSIP1 gene. This alteration results from a A to G substitution at nucleotide position 1436, causing the asparagine (N) at amino acid position 479 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
