The c.2716T>A (p.F906I) alteration is located in exon 22 (coding exon 22) of the FAM13A gene. This alteration results from a T to A substitution at nucleotide position 2716, causing the phenylalanine (F) at amino acid position 906 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
