Collection Method:clinical testing

The c.334G>A (p.E112K) alteration is located in exon 4 (coding exon 1) of the CCDC102B gene. This alteration results from a G to A substitution at nucleotide position 334, causing the glutamic acid (E) at amino acid position 112 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
