Ambry Genetics

Feb 27, 2024

The c.1117G>C (p.D373H) alteration is located in exon 11 (coding exon 11) of the CASC1 gene. This alteration results from a G to C substitution at nucleotide position 1117, causing the aspartic acid (D) at amino acid position 373 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
