Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 0P and 2B. BP6BS2_Supporting

The ENST00000285071.9(FLCN):c.1265C>T(p.Pro422Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000428 in 1,613,710 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P422R) has been classified as Uncertain significance.

Genes affected

FLCN (HGNC:27310): (folliculin) This gene is located within the Smith-Magenis syndrome region on chromosome 17. Mutations in this gene are associated with Birt-Hogg-Dube syndrome, which is characterized by fibrofolliculomas, renal tumors, lung cysts, and pneumothorax. Alternative splicing of this gene results in two transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -2 ACMG points.

BP6

Variant 17-17216415-G-A is Benign according to our data. Variant chr17-17216415-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 409390.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=2, Likely_benign=2}.

BS2

High AC in GnomAd4 at 7 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

This alteration is classified as likely 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. -
