Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 03, 2021The c.1304G>C (p.G435A) alteration is located in exon 8 (coding exon 8) of the TMEM143 gene. This alteration results from a G to C substitution at nucleotide position 1304, causing the glycine (G) at amino acid position 435 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
