Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 21, 2024The c.955A>T (p.T319S) alteration is located in exon 9 (coding exon 9) of the RUNDC3A gene. This alteration results from a A to T substitution at nucleotide position 955, causing the threonine (T) at amino acid position 319 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
