Summaries for SEMA7A Gene

Entrez Gene Summary for SEMA7A Gene

  • This gene encodes a member of the semaphorin family of proteins. The encoded preproprotein is proteolytically processed to generate the mature glycosylphosphatidylinositol (GPI)-anchored membrane glycoprotein. The encoded protein is found on activated lymphocytes and erythrocytes and may be involved in immunomodulatory and neuronal processes. The encoded protein carries the John Milton Hagen (JMH) blood group antigens. Mutations in this gene may be associated with reduced bone mineral density (BMD). Alternative splicing results in multiple transcript variants, at least one of which encodes an isoform that is proteolytically processed. [provided by RefSeq, Feb 2016]

Variants for SEMA7A Gene

Polymorphic Variants from UniProtKB/Swiss-Prot for SEMA7A Gene

SEM7A_HUMAN-O75326
Genetic variations in SEMA7A define the John Milton Hagen blood group system (JMH) [MIM:614745]. Three different JMH phenotypes have been identified based on the presence or absence of the high-frequency JMH antigen: JMH-weak, JMH-negative, and JMH-variant. The JMH-weak and -negative phenotypes can be either acquired or inherited and are characterized by a reduction or complete loss of JMH expression on red blood cells. Individuals with the JMH-variant phenotype are usually JMH-positive and have alloantibodies compatible with JMH-negative red blood cells. The JMH-variant phenotype results from rare SEMA7A missense variants.
