The c.326C>T (p.T109I) alteration is located in exon 3 (coding exon 3) of the TM7SF3 gene. This alteration results from a C to T substitution at nucleotide position 326, causing the threonine (T) at amino acid position 109 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
