The c.1132C>T (p.R378C) alteration is located in exon 11 (coding exon 11) of the ITFG1 gene. This alteration results from a C to T substitution at nucleotide position 1132, causing the arginine (R) at amino acid position 378 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
