Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 09, 2024The c.86G>C (p.C29S) alteration is located in exon 1 (coding exon 1) of the KRTAP2-1 gene. This alteration results from a G to C substitution at nucleotide position 86, causing the cysteine (C) at amino acid position 29 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
