Ambry Genetics

Dec 16, 2022

The c.336G>C (p.Q112H) alteration is located in exon 4 (coding exon 3) of the KATNAL1 gene. This alteration results from a G to C substitution at nucleotide position 336, causing the glutamine (Q) at amino acid position 112 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
