Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2021The c.1333C>T (p.R445C) alteration is located in exon 1 (coding exon 1) of the KRTAP16-1 gene. This alteration results from a C to T substitution at nucleotide position 1333, causing the arginine (R) at amino acid position 445 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
