Genes affected
TREX2 (HGNC:12270): (three prime repair exonuclease 2) This gene encodes a nuclear protein with 3' to 5' exonuclease activity. The encoded protein participates in double-stranded DNA break repair, and may interact with DNA polymerase delta. [provided by RefSeq, Nov 2012]
HAUS7 (HGNC:32979): (HAUS augmin like complex subunit 7) This gene encodes a subunit of the augmin complex, which regulates centrosome and mitotic spindle integrity, and is necessary for the completion of cytokinesis. The encoded protein was identified by interaction with ubiquitin C-terminal hydrolase 37. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2012]

Collection Method: clinical testing

The c.932C>T (p.T311M) alteration is located in exon 8 (coding exon 8) of the HAUS7 gene. This alteration results from a C to T substitution at nucleotide position 932, causing the threonine (T) at amino acid position 311 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
