Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 29, 2024The c.226C>A (p.R76S) alteration is located in exon 2 (coding exon 1) of the TATDN2 gene. This alteration results from a C to A substitution at nucleotide position 226, causing the arginine (R) at amino acid position 76 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
