Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 07, 2022The c.296G>A (p.R99H) alteration is located in exon 5 (coding exon 2) of the BBX gene. This alteration results from a G to A substitution at nucleotide position 296, causing the arginine (R) at amino acid position 99 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
