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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2024The c.289C>T (p.R97W) alteration is located in exon 3 (coding exon 2) of the DSN1 gene. This alteration results from a C to T substitution at nucleotide position 289, causing the arginine (R) at amino acid position 97 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
