The c.216G>C (p.R72S) alteration is located in exon 3 (coding exon 1) of the TMEM106B gene. This alteration results from a G to C substitution at nucleotide position 216, causing the arginine (R) at amino acid position 72 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
