Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 17, 2024The c.1277C>T (p.A426V) alteration is located in exon 6 (coding exon 6) of the CEACAM20 gene. This alteration results from a C to T substitution at nucleotide position 1277, causing the alanine (A) at amino acid position 426 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
