Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 13, 2023The c.2311A>G (p.T771A) 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 2311, causing the threonine (T) at amino acid position 771 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
