Genes affected
CAV1 (HGNC:1527): (caveolin 1) The scaffolding protein encoded by this gene is the main component of the caveolae plasma membranes found in most cell types. The protein links integrin subunits to the tyrosine kinase FYN, an initiating step in coupling integrins to the Ras-ERK pathway and promoting cell cycle progression. The gene is a tumor suppressor gene candidate and a negative regulator of the Ras-p42/44 mitogen-activated kinase cascade. Caveolin 1 and caveolin 2 are located next to each other on chromosome 7 and express colocalizing proteins that form a stable hetero-oligomeric complex. Mutations in this gene have been associated with Berardinelli-Seip congenital lipodystrophy. Alternatively spliced transcripts encode alpha and beta isoforms of caveolin 1.[provided by RefSeq, Mar 2010]

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.448A>G (p.I150V) alteration is located in exon 3 (coding exon 3) of the CAV1 gene. This alteration results from a A to G substitution at nucleotide position 448, causing the isoleucine (I) at amino acid position 150 to be replaced by a valine (V). The in silico prediction for the p.I150V alteration is inconclusive. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
