Genes affected
SIM1 (HGNC:10882): (SIM bHLH transcription factor 1) SIM1 and SIM2 genes are Drosophila single-minded (sim) gene homologs. SIM1 transcript was detected only in fetal kidney out of various adult and fetal tissues tested. Since the sim gene plays an important role in Drosophila development and has peak levels of expression during the period of neurogenesis,it was proposed that the human SIM gene is a candidate for involvement in certain dysmorphic features (particularly the facial and skull characteristics), abnormalities of brain development, and/or cognitive disability of Down syndrome.

Uncertain significance, criteria provided, single submitterclinical testingPreventionGenetics, part of Exact SciencesSep 14, 2023The SIM1 c.1894C>T variant is predicted to result in the amino acid substitution p.His632Tyr. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.011% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/6-100838644-G-A). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
