Ambry Genetics

Dec 15, 2022

The c.68C>T (p.T23I) alteration is located in exon 1 (coding exon 1) of the HYPK gene. This alteration results from a C to T substitution at nucleotide position 68, causing the threonine (T) at amino acid position 23 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
