The c.2272T>G (p.F758V) alteration is located in exon 22 (coding exon 21) of the CC2D1B gene. This alteration results from a T to G substitution at nucleotide position 2272, causing the phenylalanine (F) at amino acid position 758 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
