Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2022The c.691C>T (p.R231W) alteration is located in exon 5 (coding exon 4) of the TMEM219 gene. This alteration results from a C to T substitution at nucleotide position 691, causing the arginine (R) at amino acid position 231 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
