Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 05, 2021The c.554A>G (p.N185S) alteration is located in exon 5 (coding exon 4) of the TMEM39A gene. This alteration results from a A to G substitution at nucleotide position 554, causing the asparagine (N) at amino acid position 185 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
