Ambry Genetics

Apr 12, 2023

The c.830T>C (p.L277P) alteration is located in exon 4 (coding exon 3) of the SCARA5 gene. This alteration results from a T to C substitution at nucleotide position 830, causing the leucine (L) at amino acid position 277 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
