Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 22, 2021The c.77G>T (p.G26V) alteration is located in exon 2 (coding exon 1) of the TMEM187 gene. This alteration results from a G to T substitution at nucleotide position 77, causing the glycine (G) at amino acid position 26 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
