Genes affected
TMEFF1 (HGNC:11866): (transmembrane protein with EGF like and two follistatin like domains 1) Predicted to enable signaling receptor binding activity. Predicted to be involved in animal organ morphogenesis; neuron projection development; and tissue development. Located in plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]
MSANTD3-TMEFF1 (HGNC:38838): (MSANTD3-TMEFF1 readthrough) This locus represents naturally occurring read-through transcription from the neighboring MSANTD3 (Myb/SANT-like DNA-binding domain containing 3) and TMEFF1 (transmembrane protein with EGF-like and two follistatin-like domains 1) genes. The read-through transcript encodes a fusion protein that shares sequence identity with the products of each individual gene. [provided by RefSeq, Aug 2013]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 08, 2024The c.442G>A (p.V148I) alteration is located in exon 2 (coding exon 2) of the MSANTD3-TMEFF1 gene. This alteration results from a G to A substitution at nucleotide position 442, causing the valine (V) at amino acid position 148 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
