Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2023The c.754G>T (p.A252S) alteration is located in exon 7 (coding exon 7) of the VTA1 gene. This alteration results from a G to T substitution at nucleotide position 754, causing the alanine (A) at amino acid position 252 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
