The c.772A>T (p.I258F) alteration is located in exon 4 (coding exon 4) of the FAM185A gene. This alteration results from a A to T substitution at nucleotide position 772, causing the isoleucine (I) at amino acid position 258 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
