Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.722G>A (p.R241Q) alteration is located in exon 6 (coding exon 6) of the TMEM206 gene. This alteration results from a G to A substitution at nucleotide position 722, causing the arginine (R) at amino acid position 241 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
