Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 28, 2021The c.844G>A (p.E282K) alteration is located in exon 11 (coding exon 10) of the TMEM175 gene. This alteration results from a G to A substitution at nucleotide position 844, causing the glutamic acid (E) at amino acid position 282 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
