Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 24, 2022The c.299G>C (p.W100S) alteration is located in exon 2 (coding exon 1) of the TMEM239 gene. This alteration results from a G to C substitution at nucleotide position 299, causing the tryptophan (W) at amino acid position 100 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
