Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 06, 2024The c.218T>C (p.I73T) alteration is located in exon 3 (coding exon 2) of the TUBD1 gene. This alteration results from a T to C substitution at nucleotide position 218, causing the isoleucine (I) at amino acid position 73 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
