The c.167G>C (p.R56T) alteration is located in exon 4 (coding exon 4) of the MORF4L1 gene. This alteration results from a G to C substitution at nucleotide position 167, causing the arginine (R) at amino acid position 56 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
