Genes affected
SFSWAP (HGNC:10790): (splicing factor SWAP) This gene encodes a human homolog of Drosophila splicing regulatory protein. This gene autoregulates its expression by control of splicing of its first two introns. In addition, it also regulates the splicing of fibronectin and CD45 genes. Two transcript variants encoding different isoforms have been identified. [provided by RefSeq, May 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 20, 2024The c.813C>G (p.N271K) alteration is located in exon 5 (coding exon 5) of the SFSWAP gene. This alteration results from a C to G substitution at nucleotide position 813, causing the asparagine (N) at amino acid position 271 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
