Genes affected

TAFA3 (HGNC:21590): (TAFA chemokine like family member 3) This gene is a member of the TAFA family which is composed of five highly homologous genes that encode small secreted proteins. These proteins contain conserved cysteine residues at fixed positions, and are distantly related to MIP-1alpha, a member of the CC-chemokine family. The TAFA proteins are predominantly expressed in specific regions of the brain, and are postulated to function as brain-specific chemokines or neurokines, that act as regulators of immune and nervous cells. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Nov 2011]

The c.409A>G (p.T137A) alteration is located in exon 4 (coding exon 3) of the FAM19A3 gene. This alteration results from a A to G substitution at nucleotide position 409, causing the threonine (T) at amino acid position 137 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
