The c.1133C>A (p.T378K) alteration is located in exon 3 (coding exon 2) of the TMEM168 gene. This alteration results from a C to A substitution at nucleotide position 1133, causing the threonine (T) at amino acid position 378 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
