Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 16, 2024The c.61G>C (p.V21L) alteration is located in exon 2 (coding exon 1) of the TMEM140 gene. This alteration results from a G to C substitution at nucleotide position 61, causing the valine (V) at amino acid position 21 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
