Genes affected

HAUS3 (HGNC:28719): (HAUS augmin like complex subunit 3) This gene encodes a component of the HAUS augmin-like protein complex, which plays a key role in cytokinesis and mitosis. Disruption of the encoded protein causes mitotic defects resulting from fragmentation of centrosomes and microtubule destabilization. This gene shares its 5' exons with some transcripts from overlapping GeneID: 353497, which encodes a DNA polymerase. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2014]

HAUS3 links:

POLN (HGNC:18870): (DNA polymerase nu) This gene encodes a DNA polymerase type-A family member. The encoded protein plays a role in DNA repair and homologous recombination. This gene shares its 5' exons with some transcripts from overlapping GeneID: 79441, which encodes an augmentin-like protein complex subunit. [provided by RefSeq, Dec 2014]

Ambry Genetics

Dec 08, 2023

The c.1678T>G (p.L560V) alteration is located in exon 5 (coding exon 4) of the HAUS3 gene. This alteration results from a T to G substitution at nucleotide position 1678, causing the leucine (L) at amino acid position 560 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
