The c.1897A>T (p.I633F) alteration is located in exon 8 (coding exon 8) of the FAM171A1 gene. This alteration results from a A to T substitution at nucleotide position 1897, causing the isoleucine (I) at amino acid position 633 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
