Variant summary

Our verdict is Likely benign. The variant received -4 ACMG points: 1P and 5B. PP3 BP6 BS2

The NM_144997.7(FLCN):​c.1637A>G​(p.Asn546Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000173 in 1,614,110 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 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. N546D) 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]

ENSG00000264187 (HGNC:):

MPRIP (HGNC:30321): (myosin phosphatase Rho interacting protein) Enables cadherin binding activity. Predicted to be involved in actin filament organization. Located in actin cytoskeleton and cytosol. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Likely_benign. The variant received -4 ACMG points.

• PP3: MetaRNN computational evidence supports a deleterious effect, 0.838
• BP6: Variant 17-17213758-T-C is Benign according to our data. Variant chr17-17213758-T-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 485586.
• BS2: High AC in GnomAdExome4 at 25 AD gene.
