Ambry Genetics

Feb 27, 2024

The c.673T>C (p.Y225H) alteration is located in exon 1 (coding exon 1) of the CAPN8 gene. This alteration results from a T to C substitution at nucleotide position 673, causing the tyrosine (Y) at amino acid position 225 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
