Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 10, 2024The c.2040G>T (p.W680C) alteration is located in exon 5 (coding exon 4) of the TMEM168 gene. This alteration results from a G to T substitution at nucleotide position 2040, causing the tryptophan (W) at amino acid position 680 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
