Genes affected

FABP5 (HGNC:3560): (fatty acid binding protein 5) This gene encodes the fatty acid binding protein found in epidermal cells, and was first identified as being upregulated in psoriasis tissue. Fatty acid binding proteins are a family of small, highly conserved, cytoplasmic proteins that bind long-chain fatty acids and other hydrophobic ligands. FABPs may play roles in fatty acid uptake, transport, and metabolism. Polymorphisms in this gene are associated with type 2 diabetes. The human genome contains many pseudogenes similar to this locus.[provided by RefSeq, Feb 2011]

The c.98G>A (p.R33Q) alteration is located in exon 2 (coding exon 2) of the FABP5 gene. This alteration results from a G to A substitution at nucleotide position 98, causing the arginine (R) at amino acid position 33 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
