Genes affected
HAUS4 (HGNC:20163): (HAUS augmin like complex subunit 4) This gene encodes a subunit of the centrosome complex termed the human augmin complex. The encoded protein localizes to the spindle microtubules and may play a role in mitotic spindle assembly and maintenance of centrosome integrity during cell division. Alternate splicing results in multiple transcript variants. A pseudogene of this gene is found on chromosome 1. [provided by RefSeq, Oct 2009]
PRMT5-DT (HGNC:55482): (PRMT5 divergent transcript)

The c.1049A>G (p.N350S) alteration is located in exon 10 (coding exon 9) of the HAUS4 gene. This alteration results from a A to G substitution at nucleotide position 1049, causing the asparagine (N) at amino acid position 350 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
