Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 07, 2024The c.970G>A (p.V324I) alteration is located in exon 1 (coding exon 1) of the CABS1 gene. This alteration results from a G to A substitution at nucleotide position 970, causing the valine (V) at amino acid position 324 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
