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.683A>G (p.K228R) alteration is located in exon 8 (coding exon 7) of the SNUPN gene. This alteration results from a A to G substitution at nucleotide position 683, causing the lysine (K) at amino acid position 228 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
