The c.644G>A (p.R215Q) alteration is located in exon 10 (coding exon 10) of the FAM133B gene. This alteration results from a G to A substitution at nucleotide position 644, causing the arginine (R) at amino acid position 215 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
