The c.365C>A (p.T122K) alteration is located in exon 6 (coding exon 4) of the CC2D2B gene. This alteration results from a C to A substitution at nucleotide position 365, causing the threonine (T) at amino acid position 122 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
