Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.50G>A (p.G17E) alteration is located in exon 1 (coding exon 1) of the TMEM207 gene. This alteration results from a G to A substitution at nucleotide position 50, causing the glycine (G) at amino acid position 17 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
