Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 24, 2022The c.1040C>G (p.T347R) alteration is located in exon 7 (coding exon 7) of the TMEM143 gene. This alteration results from a C to G substitution at nucleotide position 1040, causing the threonine (T) at amino acid position 347 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
