Genes affected
SIPA1L1 (HGNC:20284): (signal induced proliferation associated 1 like 1) Predicted to enable GTPase activator activity; actin filament binding activity; and protein kinase binding activity. Predicted to be involved in several processes, including actin cytoskeleton organization; activation of GTPase activity; and regulation of postsynapse organization. Located in actin cytoskeleton and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 03, 2023The c.109C>T (p.R37W) alteration is located in exon 2 (coding exon 1) of the SIPA1L1 gene. This alteration results from a C to T substitution at nucleotide position 109, causing the arginine (R) at amino acid position 37 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
