Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 02, 2023The c.1489A>C (p.I497L) alteration is located in exon 1 (coding exon 1) of the KRTAP16-1 gene. This alteration results from a A to C substitution at nucleotide position 1489, causing the isoleucine (I) at amino acid position 497 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
