Genes affected
SPATA7 (HGNC:20423): (spermatogenesis associated 7) This gene, originally isolated from testis, is also expressed in retina. Mutations in this gene are associated with Leber congenital amaurosis and juvenile retinitis pigmentosa. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2010]

Leber congenital amaurosis 3 Pathogenic:2Other:1
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 11, 2019For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in SPATA7 are known to be pathogenic (PMID: 19268277, 22334370, 23847139, 26047050, 26261414). This variant has been observed in individual(s) with Leber congenital amaurosis (PMID: 19268277). ClinVar contains an entry for this variant (Variation ID: 1396). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the ExAC database. This sequence change creates a premature translational stop signal (p.Pro321Thrfs*6) in the SPATA7 gene. It is expected to result in an absent or disrupted protein product. -
