Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_001195263.2(PDZD7):​c.3098C>T​(p.Pro1033Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 10/14 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P1033S) has been classified as Uncertain significance.

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]

PDZD7 Gene-Disease associations (from GenCC):

• hearing loss, autosomal recessive

  Inheritance: Unknown Classification: DEFINITIVE Submitted by: ClinGen
• hearing loss, autosomal recessive 57

  Inheritance: AR Classification: STRONG Submitted by: Labcorp Genetics (formerly Invitae), PanelApp Australia
