not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Nov 03, 2023 | The c.787C>T (p.R263C) alteration is located in exon 8 (coding exon 8) of the VTA1 gene. This alteration results from a C to T substitution at nucleotide position 787, causing the arginine (R) at amino acid position 263 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
