This variant has no effect on SCG5 gene expression but is associated with greatly increased GREM1 expression (PMID: 22561515). embedded in sequence with complex architecture (e.g. 2 Cancer risks and other medical concerns You have an increased chance to develop multiple colorectal polyps and colorectal cancer. different types of mutations for GREM1. details regarding regions or types of variants that are covered or excluded for this test. Based on validation study results, this assay achieves >99% analytical sensitivity and specificity for single If polyps are found, colonoscopy is recommended every 1-2 years with consideration of surgery if the polyp burden becomes unmanageable by colonoscopy.

Invitae's methods also detect insertions and deletions larger than 15bp but smaller than a full exon but sensitivity In HMPS, the only causal mutation known to date affecting the GREM1 gene is an ancestral 40 kb duplication upstream of the GREM1 gene that is specifically present in individuals of Ashkenazi origins (Jaeger et al., 2012).
