Ambry Genetics

Oct 26, 2021

The c.8C>T (p.S3L) alteration is located in exon 2 (coding exon 1) of the KLHL8 gene. This alteration results from a C to T substitution at nucleotide position 8, causing the serine (S) at amino acid position 3 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
