The c.968C>T (p.T323I) alteration is located in exon 8 (coding exon 8) of the TMEM206 gene. This alteration results from a C to T substitution at nucleotide position 968, causing the threonine (T) at amino acid position 323 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
