Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 06, 2023The c.421A>T (p.N141Y) alteration is located in exon 4 (coding exon 4) of the TEX26 gene. This alteration results from a A to T substitution at nucleotide position 421, causing the asparagine (N) at amino acid position 141 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
