Genes affected
ZRSR2 (HGNC:23019): (zinc finger CCCH-type, RNA binding motif and serine/arginine rich 2) This gene encodes an essential splicing factor. The encoded protein associates with the U2 auxiliary factor heterodimer, which is required for the recognition of a functional 3' splice site in pre-mRNA splicing, and may play a role in network interactions during spliceosome assembly.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 20, 2024The c.829G>A (p.E277K) alteration is located in exon 10 (coding exon 10) of the ZRSR2 gene. This alteration results from a G to A substitution at nucleotide position 829, causing the glutamic acid (E) at amino acid position 277 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
