Genes affected

CAVIN1 (HGNC:9688): (caveolae associated protein 1) This gene encodes a protein that enables the dissociation of paused ternary polymerase I transcription complexes from the 3' end of pre-rRNA transcripts. This protein regulates rRNA transcription by promoting the dissociation of transcription complexes and the reinitiation of polymerase I on nascent rRNA transcripts. This protein also localizes to caveolae at the plasma membrane and is thought to play a critical role in the formation of caveolae and the stabilization of caveolins. This protein translocates from caveolae to the cytoplasm after insulin stimulation. Caveolae contain truncated forms of this protein and may be the site of phosphorylation-dependent proteolysis. This protein is also thought to modify lipid metabolism and insulin-regulated gene expression. Mutations in this gene result in a disorder characterized by generalized lipodystrophy and muscular dystrophy. [provided by RefSeq, Nov 2009]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -12 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.4).

BP6

Variant 17-42405320-C-T is Benign according to our data. Variant chr17-42405320-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 436447.

BP7

Synonymous conserved (PhyloP=2.04 with no splicing effect.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00122 (186/152330) while in subpopulation NFE AF = 0.00215 (146/68016). AF 95% confidence interval is 0.00186. There are 0 homozygotes in GnomAd4. There are 88 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 2 AR gene
