Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 04, 2024The 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. -
