Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2024The c.1046G>A (p.R349H) alteration is located in exon 7 (coding exon 6) of the TUBD1 gene. This alteration results from a G to A substitution at nucleotide position 1046, causing the arginine (R) at amino acid position 349 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
