TAFA5

Chr 22

TAFA chemokine like family member 5

Also known as: FAM19A5, QLLK5208, TAFA-5, UNQ5208

The protein is a small secreted brain-specific chemokine or neurokine that regulates immune and nervous cells, predominantly expressed in specific brain regions. Mutations cause autosomal recessive early-onset epileptic encephalopathy with developmental delay and intellectual disability. The gene shows moderate constraint against loss-of-function variants.
