Genes affected

SF3A2 (HGNC:10766): (splicing factor 3a subunit 2) This gene encodes subunit 2 of the splicing factor 3a protein complex. The splicing factor 3a heterotrimer includes subunits 1, 2 and 3 and is necessary for the in vitro conversion of 15S U2 snRNP into an active 17S particle that performs pre-mRNA splicing. Subunit 2 interacts with subunit 1 through its amino-terminus while the single zinc finger domain of subunit 2 plays a role in its binding to the 15S U2 snRNP. Subunit 2 may also function independently of its RNA splicing function as a microtubule-binding protein. [provided by RefSeq, Jul 2008]

The c.797C>T (p.P266L) alteration is located in exon 9 (coding exon 8) of the SF3A2 gene. This alteration results from a C to T substitution at nucleotide position 797, causing the proline (P) at amino acid position 266 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
