Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2023The c.425G>A (p.R142Q) 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 425, causing the arginine (R) at amino acid position 142 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
