Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 11, 2023The c.685G>T (p.A229S) alteration is located in exon 7 (coding exon 6) of the TMEM71 gene. This alteration results from a G to T substitution at nucleotide position 685, causing the alanine (A) at amino acid position 229 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
