Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 19, 2024The c.1013C>T (p.T338I) alteration is located in exon 9 (coding exon 9) of the RUNDC3A gene. This alteration results from a C to T substitution at nucleotide position 1013, causing the threonine (T) at amino acid position 338 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
