Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 17, 2023The c.1049A>G (p.N350S) alteration is located in exon 7 (coding exon 7) of the TMEM143 gene. This alteration results from a A to G substitution at nucleotide position 1049, causing the asparagine (N) at amino acid position 350 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
