Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 24, 2023The c.541G>A (p.V181I) alteration is located in exon 4 (coding exon 3) of the HYKK gene. This alteration results from a G to A substitution at nucleotide position 541, causing the valine (V) at amino acid position 181 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
