Genes affected

USH2A (HGNC:12601): (usherin) This gene encodes a protein that contains laminin EGF motifs, a pentaxin domain, and many fibronectin type III motifs. The protein is found in the basement membrane, and may be important in development and homeostasis of the inner ear and retina. Mutations within this gene have been associated with Usher syndrome type IIa and retinitis pigmentosa. Multiple transcript variants encoding different isoforms have been found for this gene.

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 26, 2024	This sequence change falls in intron 2 of the USH2A gene. It does not directly change the encoded amino acid sequence of the USH2A protein. This variant is present in population databases (rs374536346, gnomAD 0.009%). This variant has been observed in individual(s) with retinitis pigmentosa and/or Usher syndrome (PMID: 22334370, 27957503). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 372543). Studies have shown that this variant alters mRNA splicing and is expected to lead to the loss of protein expression (PMID: 20052763). For these reasons, this variant has been classified as Pathogenic. -
