Collection Method: clinical testing

The c.2092G>A (p.G698S) alteration is located in exon 13 (coding exon 13) of the TMEM8A gene. This alteration results from a G to A substitution at nucleotide position 2092, causing the glycine (G) at amino acid position 698 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
