Involvement in diseasei

Spermatogenic failure Y-linked 2 (SPGFY2)2 Publications
The disease may be caused by mutations affecting the gene represented in this entry. AZFc deletions in the Yq11.23 region including the DAZ genes are the most common known genetic cause of human male infertility.
Disease descriptionA disorder resulting in the absence (azoospermia) or reduction (oligozoospermia) of sperm in the semen, leading to male infertility.

Miscellaneousi

Miscellaneous

DAZ genes are prone to deletions but also to duplications. In a population of infertile men, DAZ genes deletions are associated with oligozoospermia but an increased number of DAZ genes is not a significant risk factor for spermatogenic failure.
The DAZ proteins (DAZ, DAZ2, DAZ4 and DAZ4) are all encoded by a strongly repeated region of the Y chromosome, in two clusters each comprising an inverted pair of DAZ genes. They are very similar, which gives their indidual characterization difficult. Thus, most experiments do not discriminate between the different members. One can therefore suppose that reported interactions with a DAZ protein involve all the 4 proteins.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
