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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 26, 2024The c.1846G>A (p.D616N) alteration is located in exon 12 (coding exon 12) of the EFHC2 gene. This alteration results from a G to A substitution at nucleotide position 1846, causing the aspartic acid (D) at amino acid position 616 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
