Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 03, 2024The c.26C>T (p.S9L) alteration is located in exon 2 (coding exon 1) of the HYKK gene. This alteration results from a C to T substitution at nucleotide position 26, causing the serine (S) at amino acid position 9 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
