The c.485T>C (p.M162T) alteration is located in exon 3 (coding exon 3) of the THUMPD1 gene. This alteration results from a T to C substitution at nucleotide position 485, causing the methionine (M) at amino acid position 162 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
