Genes affected
LRRC24 (HGNC:28947): (leucine rich repeat containing 24) Predicted to act upstream of or within positive regulation of synapse assembly. Predicted to be integral component of membrane. Predicted to be active in extracellular matrix and extracellular space. [provided by Alliance of Genome Resources, Apr 2022]
LRRC14 (HGNC:20419): (leucine rich repeat containing 14) This gene encodes a leucine-rich repeat-containing protein. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Dec 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2023The c.1490C>G (p.A497G) alteration is located in exon 5 (coding exon 4) of the LRRC24 gene. This alteration results from a C to G substitution at nucleotide position 1490, causing the alanine (A) at amino acid position 497 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
