The c.7033C>T (p.R2345W) alteration is located in exon 7 (coding exon 7) of the FAM186A gene. This alteration results from a C to T substitution at nucleotide position 7033, causing the arginine (R) at amino acid position 2345 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
