Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2PP3

The NM_001446.5(FABP7):c.206A>G(p.Glu69Gly) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000013 in 1,613,794 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E69K) has been classified as Uncertain significance.

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.

Ambry Genetics

Nov 21, 2022

The c.206A>G (p.E69G) alteration is located in exon 2 (coding exon 2) of the FABP7 gene. This alteration results from a A to G substitution at nucleotide position 206, causing the glutamic acid (E) at amino acid position 69 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
