Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 10, 2022The c.668A>T (p.N223I) alteration is located in exon 8 (coding exon 7) of the BZW2 gene. This alteration results from a A to T substitution at nucleotide position 668, causing the asparagine (N) at amino acid position 223 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
