Added comment: PMID:36336956 describes a 9-year-old boy with severe DD, lack of speech, pyramidal signs, and limb ataxia who had a de novo missense variant Asp126His in FEM1C ascertained by WES. The equivalent variant introduced into the nematode C.elegans resulted in disabled locomotion caused by synaptic abnormalities and not muscle dysfunction.

An alternate change Asp126Val was reported in the DDD study de novo in a patient with uncharacterised developmental delay (PMID:28135719).

The Asp126 residue (but not either of the variants above specifically) was shown to be functionally important by in vitro studies (PMID:33398170;33398168). The residue is highly conserved and located in a region of missense constraint.

Borderline green, 2 patients and an animal model. Note all evidence points to the Asp126 residue being of specific importance.
