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]

The c.439C>T (p.L147F) alteration is located in exon 5 (coding exon 4) of the HAUS4 gene. This alteration results from a C to T substitution at nucleotide position 439, causing the leucine (L) at amino acid position 147 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
