Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 01, 2022The c.254A>G (p.Y85C) alteration is located in exon 4 (coding exon 3) of the HMGXB4 gene. This alteration results from a A to G substitution at nucleotide position 254, causing the tyrosine (Y) at amino acid position 85 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
