Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 24, 2022The c.76G>A (p.D26N) alteration is located in exon 2 (coding exon 2) of the TEX40 gene. This alteration results from a G to A substitution at nucleotide position 76, causing the aspartic acid (D) at amino acid position 26 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
