Clinical Significance
PAX genes are a family of developmental control genes
that encode nuclear transcription factors and have been
implicated in the control of mammalian development.
PAX-5 is a B-cell specific transcription factor that is
expressed in pro B-cells, pre-B, and mature B cells, and
subsequently in all stages of B-cell development, until
that plasma cell stage in which it is down regulated.
