Genes affected
LRFN4 (HGNC:28456): (leucine rich repeat and fibronectin type III domain containing 4) Predicted to be involved in regulation of postsynaptic density assembly; regulation of presynapse assembly; and synaptic membrane adhesion. Predicted to be located in plasma membrane. Predicted to be active in GABA-ergic synapse; cell surface; and glutamatergic synapse. Predicted to be integral component of postsynaptic density membrane. [provided by Alliance of Genome Resources, Apr 2022]
PC (HGNC:8636): (pyruvate carboxylase) This gene encodes pyruvate carboxylase, which requires biotin and ATP to catalyse the carboxylation of pyruvate to oxaloacetate. The active enzyme is a homotetramer arranged in a tetrahedron which is located exclusively in the mitochondrial matrix. Pyruvate carboxylase is involved in gluconeogenesis, lipogenesis, insulin secretion and synthesis of the neurotransmitter glutamate. Mutations in this gene have been associated with pyruvate carboxylase deficiency. Alternatively spliced transcript variants with different 5' UTRs, but encoding the same protein, have been found for this gene. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 27, 2023The c.1246G>A (p.A416T) alteration is located in exon 1 (coding exon 1) of the LRFN4 gene. This alteration results from a G to A substitution at nucleotide position 1246, causing the alanine (A) at amino acid position 416 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
