Ambry Genetics

Mar 04, 2024

The c.605A>G (p.H202R) alteration is located in exon 4 (coding exon 3) of the HYKK gene. This alteration results from a A to G substitution at nucleotide position 605, causing the histidine (H) at amino acid position 202 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
