Genes affected

GEMIN2 (HGNC:10884): (gem nuclear organelle associated protein 2) This gene encodes one of the proteins found in the SMN complex, which consists of several gemin proteins and the protein known as the survival of motor neuron protein. The SMN complex is localized to a subnuclear compartment called gems (gemini of coiled bodies) and is required for assembly of spliceosomal snRNPs and for pre-mRNA splicing. This protein interacts directly with the survival of motor neuron protein and it is required for formation of the SMN complex. A knockout mouse targeting the mouse homolog of this gene exhibited disrupted snRNP assembly and motor neuron degeneration. [provided by RefSeq, Aug 2011]

The c.75G>T (p.M25I) alteration is located in exon 1 (coding exon 1) of the GEMIN2 gene. This alteration results from a G to T substitution at nucleotide position 75, causing the methionine (M) at amino acid position 25 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
