Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 11, 2021The c.604C>T (p.L202F) alteration is located in exon 5 (coding exon 4) of the TUBD1 gene. This alteration results from a C to T substitution at nucleotide position 604, causing the leucine (L) at amino acid position 202 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
