The c.2701G>A (p.A901T) alteration is located in exon 18 (coding exon 17) of the TUBGCP2 gene. This alteration results from a G to A substitution at nucleotide position 2701, causing the alanine (A) at amino acid position 901 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
