Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 03, 2022The c.11G>A (p.R4Q) alteration is located in exon 2 (coding exon 2) of the TMEM39B gene. This alteration results from a G to A substitution at nucleotide position 11, causing the arginine (R) at amino acid position 4 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
