Genes affected
AFG2A (HGNC:18119): (AFG2 AAA ATPase homolog A) This gene encodes a member of the ATPase associated with diverse activities family, whose members are defined by a highly conserved ATPase domain. Members of this family participate in diverse cellular processes that include membrane fusion, DNA replication, microtubule severing, and protein degradation. The protein encoded by this gene has a putative mitochondrial targeting sequence and has been proposed to function in maintenance of mitochondrial function and integrity during mouse spermatogenesis. Allelic variants in this gene have been associated with epilepsy, hearing loss, and cognitive disability syndrome. Alternative splicing results in multiple transcript variants.

Uncertain significance, criteria provided, single submitter | clinical testing | Baylor Genetics | Jan 10, 2020 | This variant was determined to be of uncertain significance according to ACMG Guidelines, 2015 [PMID:25741868]. - |
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Feb 11, 2022 | This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 385 of the SPATA5 protein (p.Pro385Leu). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with SPATA5-related conditions. ClinVar contains an entry for this variant (Variation ID: 475716). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C15"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
