Genes affected

DSN1 (HGNC:16165): (DSN1 component of MIS12 kinetochore complex) This gene encodes a kinetochore protein that functions as part of the minichromosome instability-12 centromere complex. The encoded protein is required for proper kinetochore assembly and progression through the cell cycle. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2009]

The c.945G>T (p.K315N) alteration is located in exon 10 (coding exon 9) of the DSN1 gene. This alteration results from a G to T substitution at nucleotide position 945, causing the lysine (K) at amino acid position 315 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
