Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 03, 2024The c.166T>A (p.C56S) alteration is located in exon 1 (coding exon 1) of the KRTAP11-1 gene. This alteration results from a T to A substitution at nucleotide position 166, causing the cysteine (C) at amino acid position 56 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
