HSD3

HSD3
PFAM accession number:PF15244
Interpro abstract (IPR029357):

This entry represents the spermatogenesis-associated protein 7 (SPATA7, also known as HSD3). It was first identified in human spermatocytes. Later on, it was also found expressed in multiple layers of the mature mouse retina [(PUBMED:19268277)]. Mutations in SPATA7 cause Leber congenital amaurosis 3 (LCA3), which is a severe dystrophy of the retina, typically becoming evident in the first years of life [(PUBMED:19268277), (PUBMED:20104588)]. Mutations in SPATA7 also cause autosomal recessive retinitis pigmentosa (ARRP), which is a retinal dystrophy belonging to the group of pigmentary retinopathies [(PUBMED:19268277)].
