Comment:

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease.

Comment:

Variant summary: The c.1233G>A (p.Glu441Glu) variant in FLCN affects a non-conserved nucleotide, resulting in a synonymous change. 5/5 splice-tools in Alamut predict no significant effect on splicing, although these predictions have yet to be confirmed by functional studies. This variant is found in 1437/117988 control chromosomes (58 homozygotes) at a frequency of 0.0121792, which is about 9743 times of the maximal expected frequency of a pathogenic allele (0.0000013), strong evidence that this variant is benign. In addition, multiple reputable clinical laboratories have classified this variant as benign. Taken together, this variant was classified as benign.

Comment:

Glu411Glu in exon 11 of FLCN: This variant is not expected to have clinical sign ificance because it does not alter an amino acid residue and is not located with in the splice consensus sequence. It has been identified in 10.6% (468/4406) of African American chromosomes from a broad population by the NHLBI Exome Sequenci ng Project (http://evs.gs.washington.edu/EVS; dbSNP rs61750032).

Comment:

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
