Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 05, 2022The c.647G>T (p.W216L) alteration is located in exon 4 (coding exon 4) of the TMEM156 gene. This alteration results from a G to T substitution at nucleotide position 647, causing the tryptophan (W) at amino acid position 216 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
