The c.1649C>G (p.T550S) alteration is located in exon 5 (coding exon 4) of the TMEM168 gene. This alteration results from a C to G substitution at nucleotide position 1649, causing the threonine (T) at amino acid position 550 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
