Genes affected

SNUPN (HGNC:14245): (snurportin 1) The nuclear import of the spliceosomal snRNPs U1, U2, U4 and U5, is dependent on the presence of a complex nuclear localization signal. The latter is composed of the 5'-2,2,7-terminal trimethylguanosine (m3G) cap structure of the U snRNA and the Sm core domain. The protein encoded by this gene interacts specifically with m3G-cap and functions as an snRNP-specific nuclear import receptor. Alternatively spliced transcript variants encoding the same protein have been identified for this gene. [provided by RefSeq, Jul 2008]

The c.367G>A (p.V123M) alteration is located in exon 4 (coding exon 3) of the SNUPN gene. This alteration results from a G to A substitution at nucleotide position 367, causing the valine (V) at amino acid position 123 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
