Variant summary

Our verdict is Benign. The variant received -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBA1

The NM_005068.3(SIM1):c.1054C>A(p.Pro352Thr) variant causes a missense change. The variant allele was found at a frequency of 0.15 in 1,613,500 control chromosomes in the GnomAD database, including 21,637 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P352S) has been classified as Uncertain significance.

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.
