Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 18, 2023The c.278G>A (p.R93Q) alteration is located in exon 3 (coding exon 3) of the VTI1B gene. This alteration results from a G to A substitution at nucleotide position 278, causing the arginine (R) at amino acid position 93 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
