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: Uncertain_significance. The variant received 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.3099141).

The c.563A>G (p.D188G) alteration is located in exon 7 (coding exon 6) of the HAUS4 gene. This alteration results from a A to G substitution at nucleotide position 563, causing the aspartic acid (D) at amino acid position 188 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
