Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2021The c.67G>T (p.V23L) alteration is located in exon 1 (coding exon 1) of the TMEM196 gene. This alteration results from a G to T substitution at nucleotide position 67, causing the valine (V) at amino acid position 23 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
