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.

Microcephaly-intellectual disability-sensorineural hearing loss-epilepsy-abnormal muscle tone syndrome Pathogenic:2
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpAug 16, 2022This sequence change creates a premature translational stop signal (p.Arg186*) in the SPATA5 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SPATA5 are known to be pathogenic (PMID: 26299366). This variant is present in population databases (rs796052095, gnomAD 0.003%). This premature translational stop signal has been observed in individuals with syndromic epilepsy (PMID: 26299366). ClinVar contains an entry for this variant (Variation ID: 204306). For these reasons, this variant has been classified as Pathogenic. -
