Genes affected

PLIN1 (HGNC:9076): (perilipin 1) The protein encoded by this gene coats lipid storage droplets in adipocytes, thereby protecting them until they can be broken down by hormone-sensitive lipase. The encoded protein is the major cAMP-dependent protein kinase substrate in adipocytes and, when unphosphorylated, may play a role in the inhibition of lipolysis. Alternatively spliced transcript variants varying in the 5' UTR, but encoding the same protein, have been found for this gene. [provided by RefSeq, Feb 2009]

PLIN1 Gene-Disease associations (from GenCC):

• PLIN1-related familial partial lipodystrophy

  Inheritance: AD Classification: STRONG, SUPPORTIVE, NO_KNOWN Submitted by: Labcorp Genetics (formerly Invitae), Genomics England PanelApp, Ambry Genetics, Orphanet

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.8).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.702 is higher than 0.05.
