Genes affected

CIDEC (HGNC:24229): (cell death inducing DFFA like effector c) This gene encodes a member of the cell death-inducing DNA fragmentation factor-like effector family. Members of this family play important roles in apoptosis. The encoded protein promotes lipid droplet formation in adipocytes and may mediate adipocyte apoptosis. This gene is regulated by insulin and its expression is positively correlated with insulin sensitivity. Mutations in this gene may contribute to insulin resistant diabetes. A pseudogene of this gene is located on the short arm of chromosome 3. Alternatively spliced transcript variants that encode different isoforms have been observed for this gene.

The c.424C>T (p.R142C) alteration is located in exon 5 (coding exon 4) of the CIDEC gene. This alteration results from a C to T substitution at nucleotide position 424, causing the arginine (R) at amino acid position 142 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
