Genes affected
TAFA5 (HGNC:21592): (TAFA chemokine like family member 5) 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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 22, 2023The c.184G>A (p.A62T) alteration is located in exon 2 (coding exon 2) of the FAM19A5 gene. This alteration results from a G to A substitution at nucleotide position 184, causing the alanine (A) at amino acid position 62 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
