Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 09, 2021The c.307C>T (p.R103C) alteration is located in exon 2 (coding exon 1) of the TMEM187 gene. This alteration results from a C to T substitution at nucleotide position 307, causing the arginine (R) at amino acid position 103 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
