Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2023The c.884A>G (p.N295S) alteration is located in exon 6 (coding exon 6) of the TMEM143 gene. This alteration results from a A to G substitution at nucleotide position 884, causing the asparagine (N) at amino acid position 295 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
