Genes affected

ZSCAN2 (HGNC:20994): (zinc finger and SCAN domain containing 2) The protein encoded by this gene contains several copies of zinc finger motif, which is commonly found in transcriptional regulatory proteins. Studies in mice show that this gene is expressed during embryonic development, and specifically in the testis in adult mice, suggesting that it may play a role in regulating genes in germ cells. Alternative splicing of this gene results in several transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.227C>A (p.A76E) alteration is located in exon 2 (coding exon 1) of the ZSCAN2 gene. This alteration results from a C to A substitution at nucleotide position 227, causing the alanine (A) at amino acid position 76 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
