Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 13, 2023The c.758G>A (p.R253Q) alteration is located in exon 5 (coding exon 4) of the TUBD1 gene. This alteration results from a G to A substitution at nucleotide position 758, causing the arginine (R) at amino acid position 253 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
