Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 01, 2022The c.794G>T (p.W265L) alteration is located in exon 6 (coding exon 6) of the CWH43 gene. This alteration results from a G to T substitution at nucleotide position 794, causing the tryptophan (W) at amino acid position 265 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
