Ambry Genetics

Mar 14, 2023

The c.961G>T (p.A321S) alteration is located in exon 4 (coding exon 4) of the KLHL1 gene. This alteration results from a G to T substitution at nucleotide position 961, causing the alanine (A) at amino acid position 321 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
