Genes affected
TMEM38A (HGNC:28462): (transmembrane protein 38A) Predicted to enable potassium channel activity. Predicted to act upstream of or within several processes, including cellular response to caffeine; inorganic cation transmembrane transport; and regulation of cardiac muscle contraction by regulation of the release of sequestered calcium ion. Located in extracellular exosome. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 14, 2021The c.94G>C (p.V32L) alteration is located in exon 1 (coding exon 1) of the TMEM38A gene. This alteration results from a G to C substitution at nucleotide position 94, causing the valine (V) at amino acid position 32 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
