Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 30, 2021The c.496C>T (p.R166W) alteration is located in exon 4 (coding exon 4) of the TEX40 gene. This alteration results from a C to T substitution at nucleotide position 496, causing the arginine (R) at amino acid position 166 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
