Title: Novel homozygous variant in the PDZD7 gene in a family with nonsyndromic sensorineural hearing loss.
PDZD7 can be an important causative gene for moderate to severe ARNSHL in Koreans. Moreover, at least some, if not all, p.Arg164Trp alleles in Koreans could exert a potential founder effect and arise from diverse haplotypes as a mutational hot spot.
Title: Identification of a Potential Founder Effect of a Novel PDZD7 Variant Involved in Moderate-to-Severe Sensorineural Hearing Loss in Koreans.
Three mutations in PDZD7 gene linked to autosomal recessive non-syndromic hearing loss (ARNSHL) were identified in a Chinese pedigree. The findings expand not only our knowledge of genetic causes of ARNSHL, but also PDZD7 genes mutation spectrum of the disease. They will aid personalized genetic counseling, molecular diagnostics and clinical management of this condition.

This is the first report to identify PDZD7 as an ARNSHL-associated gene in the Chinese population. Our finding could expand the pathogenic spectrum and strengthens the clinical diagnostic role of the PDZD7 gene in ARNSHL patients.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

Status: REVIEWED

Description

Transcript Variant: This variant (3) uses an alternate splice site in the coding region, which results in a frameshift, lacks multiple exons in the 3' coding region, and has a distinct 3' terminal exon, resulting in a distinct 3' coding region and 3' UTR compared to variant 1. It encodes isoform 3, which has a shorter and distinct C-terminus, compared to isoform 1.
