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 FLCN variant, c.397-14C>T is located at a non-conserved intronic position, not widely known to affect splicing, with 5/5 in silico programs via Alamut predicting no significant effect on splicing, although these predictions have yet to be functionally assessed. The variant of interest is observed in the large, broad control population, ExAC, with an allele frequency of 20124/41572 (1/2 including 4822 homozygotes), which significantly exceeds the estimated maximum expected allele frequency for a pathogenic FLCN variant of 1/769230. The variant of interest has also been reported by multiple reputable clinical laboratories as "benign." Therefore, the variant of interest has been classified as Benign.

Comment:

397-14C>T in intron 5 of FLCN: This variant is not expected to have clinical sig nificance because it has been identified in 48.5% (4163/8588) of European Americ an chromosomes from a broad population by the NHLBI Exome Sequencing Project (ht tp://evs.gs.washington.edu/EVS; dbSNP rs1736219).
