The c.2729T>C (p.I910T) alteration is located in exon 15 (coding exon 15) of the FAM184B gene. This alteration results from a T to C substitution at nucleotide position 2729, causing the isoleucine (I) at amino acid position 910 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
