The c.733G>T (p.A245S) alteration is located in exon 5 (coding exon 4) of the TUBD1 gene. This alteration results from a G to T substitution at nucleotide position 733, causing the alanine (A) at amino acid position 245 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
