Genes affected

EFCAB9 (HGNC:34530): (EF-hand calcium binding domain 9) This gene encodes a protein with a C-terminal EF-hand calcium-binding domain similar to that found in penta-EF-hand (PEF) protein family members. The EF-hand is a helix-loop-helix structure with a canonical twelve-residue sequence that coordinates a calcium molecule with pentagonal bipyramidal symmetry. [provided by RefSeq, Jul 2017]

Collection Method: clinical testing

The c.230G>A (p.G77D) alteration is located in exon 2 (coding exon 2) of the EFCAB9 gene. This alteration results from a G to A substitution at nucleotide position 230, causing the glycine (G) at amino acid position 77 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
