Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 01, 2022The c.902A>G (p.Q301R) alteration is located in exon 6 (coding exon 5) of the TUBD1 gene. This alteration results from a A to G substitution at nucleotide position 902, causing the glutamine (Q) at amino acid position 301 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
