Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Apr 07, 2023 | The c.1349G>T (p.G450V) alteration is located in exon 4 (coding exon 4) of the HLX gene. This alteration results from a G to T substitution at nucleotide position 1349, causing the glycine (G) at amino acid position 450 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
