The c.631A>G (p.K211E) alteration is located in exon 5 (coding exon 4) of the TUBD1 gene. This alteration results from a A to G substitution at nucleotide position 631, causing the lysine (K) at amino acid position 211 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
