Variant summary

Our verdict is Likely benign. The variant received -6 ACMG points: 2P and 8B. PM2 BP6_Very_Strong

The NM_001195263.2(PDZD7):​c.2331_2348delTAGCCGCAGCCGCAGCCG​(p.Ser778_Arg783del) variant causes a disruptive inframe deletion change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Likely benign (★★). Synonymous variant affecting the same amino acid position (i.e. R777R) has been classified as Likely benign.

Genes affected

PDZD7 (HGNC:26257): (PDZ domain containing 7) This gene encodes a ciliary protein homologous to proteins which are mutated in Usher syndrome patients, and mutations and translocations involving this gene have been associated with two types of Usher syndrome. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2010]

ACMG classification

Our verdict: Likely_benign. The variant received -6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP6: Variant 10-101010540-GCGGCTGCGGCTGCGGCTA-G is Benign according to our data. Variant chr10-101010540-GCGGCTGCGGCTGCGGCTA-G is described in ClinVar as [Likely_benign]. Clinvar id is 164938.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The Arg779_Ser784del variant in PDZD7 has not been reported in the literature. T he frequency of this variant in large European American and African American pop ulations sequenced by the NHLBI Exome Sequencing Project (http://evs.gs.washingt on.edu/EVS/) was not reported because coverage at this position was insufficient or unavailable. This in-frame deletion lies in a variable Arg-Ser repeat region that is not conserved in species including other primates. Furthermore, there i s inconclusive evidence as to the role of the PDZD7 gene in hearing loss with on ly one case report suggesting PDZD7 could cause nonsyndromic hearing loss based upon a patient with a homozygous translocation that disrupts the long alternate isoform of PDZD7 (Schneider 2009). In summary, this variant is likely benign bas ed on its presence in a variable repeat region and lack of conservation across s pecies. -
