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.

The c.1297C>T (p.R433C) alteration is located in exon 11 (coding exon 11) of the ZRSR2 gene. This alteration results from a C to T substitution at nucleotide position 1297, causing the arginine (R) at amino acid position 433 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
