Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 21, 2021The c.370C>T (p.R124W) alteration is located in exon 5 (coding exon 5) of the TMEM147 gene. This alteration results from a C to T substitution at nucleotide position 370, causing the arginine (R) at amino acid position 124 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
