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.

The c.1496A>C (p.D499A) alteration is located in exon 15 (coding exon 14) of the PSIP1 gene. This alteration results from a A to C substitution at nucleotide position 1496, causing the aspartic acid (D) at amino acid position 499 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
