Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 22, 2023The c.739G>T (p.V247F) alteration is located in exon 4 (coding exon 4) of the CEACAM20 gene. This alteration results from a G to T substitution at nucleotide position 739, causing the valine (V) at amino acid position 247 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
