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]

ENSG00000259132 (HGNC:):

PRMT5-DT (HGNC:55482): (PRMT5 divergent transcript)

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.13989905).

Collection Method: clinical testing

The c.1054C>T (p.R352W) alteration is located in exon 10 (coding exon 9) of the HAUS4 gene. This alteration results from a C to T substitution at nucleotide position 1054, causing the arginine (R) at amino acid position 352 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
