Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 11, 2024The c.41A>G (p.Y14C) alteration is located in exon 1 (coding exon 1) of the KRT222 gene. This alteration results from a A to G substitution at nucleotide position 41, causing the tyrosine (Y) at amino acid position 14 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
