Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 30, 2023The c.1069C>T (p.H357Y) alteration is located in exon 8 (coding exon 8) of the BCO2 gene. This alteration results from a C to T substitution at nucleotide position 1069, causing the histidine (H) at amino acid position 357 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
