Genes affected

FNIP1 (HGNC:29418): (folliculin interacting protein 1) This gene encodes a protein that binds to the tumor suppressor protein folliculin and to AMP-activated protein kinase (AMPK). The encoded protein participates in the regulation of cellular metabolism and nutrient sensing by modulating the AMPK and target of rapamycin signaling pathways. This gene has a closely related paralog that encodes a protein with similar binding activities. Both related proteins also associate with the molecular chaperone heat shock protein-90 (Hsp90) and negatively regulate its ATPase activity and facilitate its association with folliculin.

ACMG classification

Verdict is Benign. Variant got -7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.43).
• BP6: Variant 5-131651876-A-G is Benign according to our data. Variant chr5-131651876-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 3012554.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=2.98 with no splicing effect.
• BS1: Variant frequency is greater than expected in population afr. gnomad4_exome allele frequency = 0.00000137 (2/1461852) while in subpopulation AFR AF= 0.0000597 (2/33480). AF 95% confidence interval is 0.00000989. There are 0 homozygotes in gnomad4_exome. There are 0 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck.
