Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 30, 2024The c.100T>A (p.S34T) alteration is located in exon 2 (coding exon 1) of the TELO2 gene. This alteration results from a T to A substitution at nucleotide position 100, causing the serine (S) at amino acid position 34 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
