Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 14, 2022The c.1214T>C (p.V405A) alteration is located in exon 4 (coding exon 4) of the TUBA1C gene. This alteration results from a T to C substitution at nucleotide position 1214, causing the valine (V) at amino acid position 405 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
