Submissions by phenotype
Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Aug 16, 2021 | The c.509C>T (p.A170V) alteration is located in exon 5 (coding exon 4) of the HMGB1 gene. This alteration results from a C to T substitution at nucleotide position 509, causing the alanine (A) at amino acid position 170 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
