The c.715A>T (p.I239F) alteration is located in exon 6 (coding exon 6) of the ACTR8 gene. This alteration results from a A to T substitution at nucleotide position 715, causing the isoleucine (I) at amino acid position 239 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
