Gene rating submitted by Tracy Briggs, David Gokhale and Abigal Rousseau on behalf of North West GLH for the GMS Immunology specialist test group. As discussed with the GMS Immunology Specialist Test Group during webex call 28th March 2019 and confirmed in follow up email on 20th June the Specialist Test Group all agreed there is only enough evidence to rate this gene Amber.Created: 25 Sep 2019, 3 p.m. | Last Modified: 25 Sep 2019, 3 p.m.

Comment on list classification: Amber rating not Green rating. From clinical review it was noted that this is a single variant with a founder effect so amber rating as there
is no confirmatory evidence that the variant/gene is causative (other cases or functional data). Also not sure that the SLE phenotype is the best fit for the PID panelCreated: 6 Jul 2018, 4:09 p.m.
added deletions tag. Although a deletion, it is small (1bp) so is reportable with current pipelineCreated: 6 Jul 2018, 10:56 a.m.

From PMID Al-Mayouf et al. (2011) PMID: 22019780 identified homozygosity for a 1-bp deletion (643delT) in the DNASE1L3 gene in 6 affected members of consanguineous Arab families with systemic lupus erythematosus. The mutation segregated perfectly with the disease state in a strictly mendelian, fully penetrant, and autosomal recessive fashion in all 6 families, and was not found in 192 ethnically matched controls. Haplotype analysis confirmed this to be a founder mutation. In lymphoblast cell lines from 2 patients, no DNASE1L3 transcript was detected, and tissue culture studies demonstrated that mutant DNASE1L3 completely lacks DNase activity.Created: 6 Jul 2018, 10:52 a.m.
