Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 25, 2022The c.248C>T (p.S83L) alteration is located in exon 1 (coding exon 1) of the KRTAP2-1 gene. This alteration results from a C to T substitution at nucleotide position 248, causing the serine (S) at amino acid position 83 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
