Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 18, 2021The c.857A>G (p.Q286R) alteration is located in exon 5 (coding exon 5) of the CEACAM20 gene. This alteration results from a A to G substitution at nucleotide position 857, causing the glutamine (Q) at amino acid position 286 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
