Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 22, 2023The c.856A>C (p.M286L) alteration is located in exon 5 (coding exon 4) of the HMGXB3 gene. This alteration results from a A to C substitution at nucleotide position 856, causing the methionine (M) at amino acid position 286 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
