Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 18, 2022The c.754G>A (p.A252T) alteration is located in exon 7 (coding exon 7) of the VTA1 gene. This alteration results from a G to A substitution at nucleotide position 754, causing the alanine (A) at amino acid position 252 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
