The c.2884A>T (p.I962F) alteration is located in exon 13 (coding exon 12) of the FAM135B gene. This alteration results from a A to T substitution at nucleotide position 2884, causing the isoleucine (I) at amino acid position 962 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
