Genes affected
SMTNL1 (HGNC:32394): (smoothelin like 1) The protein encoded by this gene is involved in the contraction of both striated and smooth muscle. During pregnancy, the encoded protein interacts with progesterone receptor to attenuate the expression of contractile and metabolic proteins. [provided by RefSeq, Jul 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 02, 2024The c.563A>G (p.E188G) alteration is located in exon 1 (coding exon 1) of the SMTNL1 gene. This alteration results from a A to G substitution at nucleotide position 563, causing the glutamic acid (E) at amino acid position 188 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
