Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 16, 2021The c.532A>T (p.M178L) alteration is located in exon 4 (coding exon 3) of the HMGXB3 gene. This alteration results from a A to T substitution at nucleotide position 532, causing the methionine (M) at amino acid position 178 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
