The c.619C>G (p.R207G) alteration is located in exon 4 (coding exon 4) of the FAM234B gene. This alteration results from a C to G substitution at nucleotide position 619, causing the arginine (R) at amino acid position 207 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
