Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 13, 2022The c.823G>A (p.A275T) alteration is located in exon 5 (coding exon 4) of the HMGXB4 gene. This alteration results from a G to A substitution at nucleotide position 823, causing the alanine (A) at amino acid position 275 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
