Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Nov 09, 2023 | The c.739G>C (p.V247L) alteration is located in exon 2 (coding exon 2) of the KRT77 gene. This alteration results from a G to C substitution at nucleotide position 739, causing the valine (V) at amino acid position 247 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
