The c.1583T>C (p.I528T) alteration is located in exon 16 (coding exon 16) of the ITFG1 gene. This alteration results from a T to C substitution at nucleotide position 1583, causing the isoleucine (I) at amino acid position 528 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
