Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2024The c.878C>T (p.T293I) alteration is located in exon 9 (coding exon 9) of the EXD1 gene. This alteration results from a C to T substitution at nucleotide position 878, causing the threonine (T) at amino acid position 293 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
