Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 05, 2023The c.2134A>G (p.K712E) alteration is located in exon 12 (coding exon 12) of the COBLL1 gene. This alteration results from a A to G substitution at nucleotide position 2134, causing the lysine (K) at amino acid position 712 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
