The c.679G>A (p.E227K) alteration is located in exon 4 (coding exon 3) of the CCSAP gene. This alteration results from a G to A substitution at nucleotide position 679, causing the glutamic acid (E) at amino acid position 227 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
