Genes affected
SMCR8 (HGNC:17921): (SMCR8-C9orf72 complex subunit) Enables protein kinase binding activity and protein kinase inhibitor activity. Contributes to guanyl-nucleotide exchange factor activity. Involved in negative regulation of macromolecule metabolic process; regulation of TOR signaling; and regulation of macroautophagy. Located in chromatin; cytoplasm; and nucleoplasm. Part of guanyl-nucleotide exchange factor complex. Colocalizes with Atg1/ULK1 kinase complex. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 06, 2021The c.435G>T (p.E145D) alteration is located in exon 1 (coding exon 1) of the SMCR8 gene. This alteration results from a G to T substitution at nucleotide position 435, causing the glutamic acid (E) at amino acid position 145 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
