Ambry Genetics

Mar 16, 2024

The c.89A>T (p.K30I) alteration is located in exon 2 (coding exon 2) of the GPATCH1 gene. This alteration results from a A to T substitution at nucleotide position 89, causing the lysine (K) at amino acid position 30 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
