Dec 13, 2022

The c.868A>G (p.M290V) alteration is located in exon 6 (coding exon 6) of the THUMPD2 gene. This alteration results from a A to G substitution at nucleotide position 868, causing the methionine (M) at amino acid position 290 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
