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 GeneticsFeb 21, 2024The c.619T>A (p.S207T) alteration is located in exon 7 (coding exon 6) of the DSN1 gene. This alteration results from a T to A substitution at nucleotide position 619, causing the serine (S) at amino acid position 207 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
