Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 14, 2024The c.380A>G (p.K127R) alteration is located in exon 5 (coding exon 4) of the BZW2 gene. This alteration results from a A to G substitution at nucleotide position 380, causing the lysine (K) at amino acid position 127 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
