Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 10, 2024The c.167G>T (p.G56V) alteration is located in exon 1 (coding exon 1) of the KRTAP19-1 gene. This alteration results from a G to T substitution at nucleotide position 167, causing the glycine (G) at amino acid position 56 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
