Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 23, 2023The c.620T>C (p.V207A) alteration is located in exon 1 (coding exon 1) of the CABS1 gene. This alteration results from a T to C substitution at nucleotide position 620, causing the valine (V) at amino acid position 207 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
