Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 14, 2023The c.812G>T (p.R271I) alteration is located in exon 4 (coding exon 4) of the TUBAL3 gene. This alteration results from a G to T substitution at nucleotide position 812, causing the arginine (R) at amino acid position 271 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
