The c.1108G>C (p.D370H) alteration is located in exon 1 (coding exon 1) of the CABS1 gene. This alteration results from a G to C substitution at nucleotide position 1108, causing the aspartic acid (D) at amino acid position 370 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
