Genes affected
RNPC3 (HGNC:18666): (RNA binding region (RNP1, RRM) containing 3) Two types of spliceosomes catalyze splicing of pre-mRNAs. The major U2-type spliceosome is found in all eukaryotes and removes U2-type introns, which represent more than 99% of pre-mRNA introns. The minor U12-type spliceosome is found in some eukaryotes and removes U12-type introns, which are rare and have distinct splice consensus signals. The U12-type spliceosome consists of several small nuclear RNAs and associated proteins. This gene encodes a 65K protein that is a component of the U12-type spliceosome. This protein contains two RNA recognition motifs (RRMs), suggesting that it may contact one of the small nuclear RNAs of the minor spliceosome. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.611C>T (p.A204V) alteration is located in exon 1 (coding exon 1) of the RNPC3 gene. This alteration results from a C to T substitution at nucleotide position 611, causing the alanine (A) at amino acid position 204 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
