Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 26, 2023The c.973C>T (p.P325S) alteration is located in exon 7 (coding exon 6) of the TUBD1 gene. This alteration results from a C to T substitution at nucleotide position 973, causing the proline (P) at amino acid position 325 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
