Genes affected

EFHC2 (HGNC:26233): (EF-hand domain containing 2) This gene encodes a protein which contains three DM10 domains and three calcium-binding EF-hand motifs. A related protein is encoded by a gene on chromosome 6. It has been suggested that both proteins are involved in the development of epilepsy (PMID: 15258581, 16112844) and that this gene may be associated with fear recognition in individuals with Turner syndrome.

The c.1392T>G (p.I464M) alteration is located in exon 9 (coding exon 9) of the EFHC2 gene. This alteration results from a T to G substitution at nucleotide position 1392, causing the isoleucine (I) at amino acid position 464 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
