Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 17, 2022The c.950G>T (p.S317I) alteration is located in exon 6 (coding exon 5) of the HMGXB3 gene. This alteration results from a G to T substitution at nucleotide position 950, causing the serine (S) at amino acid position 317 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
