MSANTD3 links:

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]

The c.578T>C (p.L193S) alteration is located in exon 3 (coding exon 2) of the MSANTD3 gene. This alteration results from a T to C substitution at nucleotide position 578, causing the leucine (L) at amino acid position 193 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
