Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 28, 2024The c.169C>A (p.L57I) alteration is located in exon 5 (coding exon 2) of the BBX gene. This alteration results from a C to A substitution at nucleotide position 169, causing the leucine (L) at amino acid position 57 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
