Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 01, 2023The c.419A>G (p.Y140C) alteration is located in exon 4 (coding exon 4) of the CWH43 gene. This alteration results from a A to G substitution at nucleotide position 419, causing the tyrosine (Y) at amino acid position 140 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
