Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2021The c.1289G>A (p.S430N) alteration is located in exon 9 (coding exon 8) of the TMEM39A gene. This alteration results from a G to A substitution at nucleotide position 1289, causing the serine (S) at amino acid position 430 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
