Genes affected

STAC2 (HGNC:23990): (SH3 and cysteine rich domain 2) This gene encodes a protein containing an SH3 domain and a zinc finger domain. The encoded protein has been shown to regulate calcium channel inactivation in a human cell line. Reduced expression of this gene has been observed in human heart failure.
