The moi for this gene should be changed to BOTH monoallelic and Biallelic as PMID: 34905022 & 3155024 report two cases of SSBP1-disease associated with biallelic SSBP1 variants. The variant c.380G>A p.(Arg127Gln)(MAF of 0.00004) was found with c.394A>G p.(Ile132Val)(PMID: 34905022), which had previously been found as a homozygote in a single case (PMID: 31550240).Created: 4 Jan 2022, 4:06 p.m. | Last Modified: 4 Jan 2022, 5:13 p.m.

Multiple reports indicate that missense variants in SSBP1 cause optic atrophy with variable degree of retinal degeneration. Some families in addition to ophthalmic phenotype showed systemic involvement. Recurrent variants were identified by independent study groups.
Findings were supported by functional work in animal models.Created: 4 Feb 2021, 10:28 a.m. | Last Modified: 4 Feb 2021, 10:28 a.m.

Three heterozygous missense variants in two families and two singletons. A postulated dominant-negative mechanism is supported by functional studies in zebrafish.Created: 16 Jul 2019, 3:04 p.m. | Last Modified: 16 Jul 2019, 3:04 p.m.

Variants identified to date are missense and putative mode of action is dominant-negative, therefore there is potential for exception to loss-of-function rule, but insufficient data to clearly demonstrate at the moment. There are lower than expected LoF variants in gnomAD, so cannot rule out pathogenic LoF variants.Created: 16 Jul 2019, 2:22 p.m. | Last Modified: 16 Jul 2019, 2:31 p.m.
