Genes affected

GEMIN4 (HGNC:15717): (gem nuclear organelle associated protein 4) The product of this gene is part of a large complex localized to the cytoplasm, nucleoli, and to discrete nuclear bodies called Gemini bodies (gems). The complex functions in spliceosomal snRNP assembly in the cytoplasm, and regenerates spliceosomes required for pre-mRNA splicing in the nucleus. The encoded protein directly interacts with a DEAD box protein and several spliceosome core proteins. Alternatively spliced transcript variants have been described, but their biological validity has not been determined. [provided by RefSeq, Jul 2008]

The c.2864G>A (p.R955K) alteration is located in exon 2 (coding exon 2) of the GEMIN4 gene. This alteration results from a G to A substitution at nucleotide position 2864, causing the arginine (R) at amino acid position 955 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
