The c.161T>C (p.I54T) alteration is located in exon 1 (coding exon 1) of the FAM186A gene. This alteration results from a T to C substitution at nucleotide position 161, causing the isoleucine (I) at amino acid position 54 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
