Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 06, 2022The c.419A>G (p.N140S) alteration is located in exon 5 (coding exon 5) of the TMEM147 gene. This alteration results from a A to G substitution at nucleotide position 419, causing the asparagine (N) at amino acid position 140 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
