Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 27, 2023The c.253T>G (p.C85G) alteration is located in exon 1 (coding exon 1) of the KRTAP11-1 gene. This alteration results from a T to G substitution at nucleotide position 253, causing the cysteine (C) at amino acid position 85 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
