Collection Method: clinical testing

The c.428T>C (p.I143T) alteration is located in exon 6 (coding exon 6) of the FAM206A gene. This alteration results from a T to C substitution at nucleotide position 428, causing the isoleucine (I) at amino acid position 143 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
