Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 20, 2024The c.296A>G (p.E99G) alteration is located in exon 4 (coding exon 4) of the CNBD1 gene. This alteration results from a A to G substitution at nucleotide position 296, causing the glutamic acid (E) at amino acid position 99 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
