Homo sapiens

Also known as EL3; HS2; SPH2; HSPTB1

Gene ID: 6710 | Gene type: protein coding

About SPTB

Cytogenetic location: 14q23.3 Genomic coordinates (GRCh38): 14:64,746,283-64,879,907 (from NCBI)

This gene has 7 transcripts (splice variants), 198 orthologues, 36 paralogues and is associated with 4 phenotypes. Biased expression in bone marrow (RPKM 15.7), heart (RPKM 8.2) and 8 other tissues.

Summary

This locus encodes a member of the spectrin gene family. Spectrin proteins, along with ankyrin, play a role in cell membrane organization and stability. The protein encoded by this locus functions in stability of erythrocyte membranes, and mutations in this gene have been associated with spherocytosis type 2, hereditary elliptocytosis, and neonatal hemolytic anemia. Alternatively spliced transcript variants have been described. [provided by RefSeq, Nov 2009]
