Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 25, 2024The c.541T>C (p.S181P) alteration is located in exon 5 (coding exon 5) of the KRT222 gene. This alteration results from a T to C substitution at nucleotide position 541, causing the serine (S) at amino acid position 181 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
