Genes affected

ZMAT1 (HGNC:29377): (zinc finger matrin-type 1) This gene encodes a protein containing Cys2-His2 (C2H2)-type zinc fingers, which are similar to those found in the nuclear matrix protein matrin 3. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jan 2012]
