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]

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Feb 27, 2023 | The c.707C>G (p.P236R) alteration is located in exon 9 (coding exon 8) of the SF3A2 gene. This alteration results from a C to G substitution at nucleotide position 707, causing the proline (P) at amino acid position 236 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
