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 GeneticsNov 14, 2023The c.532A>G (p.I178V) alteration is located in exon 2 (coding exon 1) of the SIPA1L1 gene. This alteration results from a A to G substitution at nucleotide position 532, causing the isoleucine (I) at amino acid position 178 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
