not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 10, 2024The c.254G>A (p.G85D) alteration is located in exon 3 (coding exon 3) of the CABP7 gene. This alteration results from a G to A substitution at nucleotide position 254, causing the glycine (G) at amino acid position 85 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
