“Genes”  

Gene

  In our body's cells, our Genes are part of a complex interactive biological system, that codes for specific proteins and expresses those proteins in response to any signals received from biological events.

Locus

  In our body's cells, Genes are specific sequences of nucleotides along a molecule of DNA (DeoxyriboNucleic Acid) which represent our functional units of Heredity.

In our body's cells, Genes are the specific segments of DeoxyriboNucleic Acid (DNA) found on chromosomes.

In our body's cells, each gene has a designated place on every chromosome, called a locus.
  Examples of subsets, concepts, subjects, topics and other related entities of genes and associated proteins include:

• X-linked genes
• Y-linked genes

“SRY Gene”  

SRY

  In our body's cells, the SRY gene, aka sex determining region Y (testis-determining factor), is one of our human genes, belonging to the SRY-box transcription factors genes.

SRY Gene

  In our body's cells, the chromosomal locus of the SRY gene is found on chromosome Y at the Yp11.2 position. **

“Histocompatibility Complex (MHC) ”  

Major Histocompatibility Complex (HLA Complex)

  In our body, Major Histocompatibility Complex (MHC), aka Histocompatibility Complex (HLA Complex), is a genetic region which contains the loci of genes which determine the structure of the serologically defined (SD) and lymphocyte-defined (LD) Transplantation Antigens.
  In our body's cells, the major Histocompatibility Complex (HLA Complex) is a large genomic region or gene family that encodes MHC molecules. The MHC protein molecules act as "signposts" to alert the immune system if a foreign material is present inside a cell.
  The major histocompatibility complex gene family (HLA gene family) contains the following genes within two subclasses:

• MHC class I genes (major histocompatibility complex class I genes), aka histocompatibility complex class I gene family (HLA class I gene family)
  • HLA-A gene (major histocompatibility complex, class I, A)
  • HLA-B gene (major histocompatibility complex, class I, B)
  • HLA-C gene (major histocompatibility complex, class I, C)
  • HLA-E gene (major histocompatibility complex, class I, E)
  • HLA-F gene (major histocompatibility complex, class I, F)

  • HLA-K gene (major histocompatibility complex, class I, K pseudogene)
  • HLA-L gene (major histocompatibility complex, class I, L pseudogene)
  • HLA-N gene (major histocompatibility complex, class I, N pseudogene)
  • HLA-P gene (major histocompatibility complex, class I, P pseudogene)
  • HLA-S gene (major histocompatibility complex, class I, S pseudogene)
  • HLA-T gene (major histocompatibility complex, class I, T pseudogene)
  • HLA-U gene (major histocompatibility complex, class I, U pseudogene)
  • HLA-V gene (major histocompatibility complex, class I, V pseudogene)
  • HLA-W gene (major histocompatibility complex, class I, W pseudogene)
  • HLA-X gene (major histocompatibility complex, class I, X pseudogene)
  • HLA-Y gene (major histocompatibility complex, class I, Y pseudogene)
  • HLA-Z gene (major histocompatibility complex, class I, Z pseudogene)
• MHC class I genes (major histocompatibility complex class I genes), aka histocompatibility complex class I gene family (HLA class I gene family)
  • HLA-DMA gene (major histocompatibility complex, class II, DM alpha)
