Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 09, 2022The c.2785G>A (p.A929T) alteration is located in exon 12 (coding exon 12) of the COBLL1 gene. This alteration results from a G to A substitution at nucleotide position 2785, causing the alanine (A) at amino acid position 929 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
