Genes affected

EFHD1 (HGNC:29556): (EF-hand domain family member D1) This gene encodes a member of the EF-hand super family of calcium binding proteins, which are involved in a variety of cellular processes including mitosis, synaptic transmission, and cytoskeletal rearrangement. The protein encoded by this gene is composed of an N-terminal disordered region, proline-rich elements, two EF-hands, and a C-terminal coiled-coil domain. This protein has been shown to associate with the mitochondrial inner membrane, and in HeLa cells, acts as a novel mitochondrial calcium ion sensor for mitochondrial flash activation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2016]

Ambry Genetics

Feb 13, 2024

The c.299A>C (p.K100T) alteration is located in exon 1 (coding exon 1) of the EFHD1 gene. This alteration results from a A to C substitution at nucleotide position 299, causing the lysine (K) at amino acid position 100 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
