Genes affected

FABP7 (HGNC:3562): (fatty acid binding protein 7) The gene encodes a small, highly conserved cytoplasmic protein that bind long-chain fatty acids and other hydrophobic ligands. The encoded protein is important in the establishment of the radial glial fiber in the developing brain. Alternative splicing and promoter usage results in multiple transcript variants encoding different isoforms. Pseudogenes of this gene are found on multiple chromosomes.

The c.205G>A (p.E69K) alteration is located in exon 2 (coding exon 2) of the FABP7 gene. This alteration results from a G to A substitution at nucleotide position 205, causing the glutamic acid (E) at amino acid position 69 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
