Genes affected

MEIS2 (HGNC:7001): (Meis homeobox 2) This gene encodes a homeobox protein belonging to the TALE ('three amino acid loop extension') family of homeodomain-containing proteins. TALE homeobox proteins are highly conserved transcription regulators, and several members have been shown to be essential contributors to developmental programs. Multiple transcript variants encoding distinct isoforms have been described for this gene. [provided by RefSeq, Jul 2008]

The c.1170C>G (p.D390E) alteration is located in exon 12 (coding exon 12) of the MEIS2 gene. This alteration results from a C to G substitution at nucleotide position 1170, causing the aspartic acid (D) at amino acid position 390 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
