Genes affected
LRIG1 (HGNC:17360): (leucine rich repeats and immunoglobulin like domains 1) Predicted to act upstream of or within several processes, including innervation; otolith morphogenesis; and sensory perception of sound. Predicted to be located in plasma membrane. Predicted to be active in extracellular matrix and extracellular space. [provided by Alliance of Genome Resources, Apr 2022]
SLC25A26 (HGNC:20661): (solute carrier family 25 member 26) This gene is a member of the mitochondrial carrier family which includes nuclear-encoded transporters localized on the inner mitochondrial membranes. Members of the family transport important small molecules across the mitochondrial inner membrane. This protein is involved in the transport of S-adenosylmethionine (SAM) into the mitochondria. Mutations in this gene are associated with combined oxidative phosphorylation deficiency 28. Alternative splicing results in multiple transcript variants encoding different isoforms.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 25, 2023The c.3149C>T (p.A1050V) alteration is located in exon 19 (coding exon 19) of the LRIG1 gene. This alteration results from a C to T substitution at nucleotide position 3149, causing the alanine (A) at amino acid position 1050 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
