Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 08, 2023The c.655G>A (p.A219T) alteration is located in exon 4 (coding exon 3) of the HMGXB3 gene. This alteration results from a G to A substitution at nucleotide position 655, causing the alanine (A) at amino acid position 219 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
