Genes affected

DLC1 (HGNC:2897): (DLC1 Rho GTPase activating protein) This gene encodes a GTPase-activating protein (GAP) that is a member of the rhoGAP family of proteins which play a role in the regulation of small GTP-binding proteins. GAP family proteins participate in signaling pathways that regulate cell processes involved in cytoskeletal changes. This gene functions as a tumor suppressor gene in a number of common cancers, including prostate, lung, colorectal, and breast cancers. Multiple transcript variants due to alternative promoters and alternative splicing have been found for this gene.[provided by RefSeq, Apr 2010]

DLC1 Gene-Disease associations (from GenCC):

• congenital heart defects, multiple types

  Inheritance: AD Classification: LIMITED Submitted by: Ambry Genetics
• colorectal cancer

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.7).
• BP6: Variant 8-13091442-A-G is Benign according to our data. Variant chr8-13091442-A-G is described in ClinVar as Benign. ClinVar VariationId is 1600292.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.711 is higher than 0.05.
