Fetal anomalies v2.0 MAB21L1 Gene migrated from ENSG00000180660 to ENSG00000180660 (gene set migration)
Fetal anomalies v1.585 MAB21L1 Zornitza Stark Phenotypes for gene: MAB21L1 were changed from Cerebellar, ocular, craniofacial, and genital syndrome OMIM#618479 to Cerebellar, ocular, craniofacial, and genital syndrome OMIM#618479; Microphthalmia MONDO:0021129, MAB21L1-related
Fetal anomalies v1.584 MAB21L1 Zornitza Stark Publications for gene: MAB21L1 were set to 30487245
Fetal anomalies v1.583 MAB21L1 Zornitza Stark Mode of inheritance for gene: MAB21L1 was changed from BIALLELIC, autosomal or pseudoautosomal to BOTH monoallelic and biallelic, autosomal or pseudoautosomal
Fetal anomalies v1.582 MAB21L1 Zornitza Stark edited their review of gene: MAB21L1: Changed mode of inheritance: BOTH monoallelic and biallelic, autosomal or pseudoautosomal
Fetal anomalies v1.582 MAB21L1 Zornitza Stark edited their review of gene: MAB21L1: Added comment: PMID:33973683 (2021) reported a heterozygous novel variant in MAB21L1 gene (c.152G>T/ p.Arg51Leu), in two family members with microphthalmia and aniridia, as well as novel or rare compound heterozygous variants of uncertain significance (c.184C>T/ p.Arg62Cys; c.-68T>C and c.658G>C/ p.Gly220Arg; c.*529A>G) in two additional probands with microphthalmia, coloboma and/or cataracts. There is also function evidence available from in vitro studies of coding variants and in vivo complementation assays using the zebrafish mab21l2 Q48Sfs*5 loss-of-function line.

PMID:36413568 (2022) reported nine patients from five families with severe aniridia and/or microphthalmia with ultrarare monoallelic missense variants altering the Arg51 codon of MAB21L1. The detected variants are c.152G>A/ p.Arg51Gln, c.152G>T/ p.Arg51Leu, c.152G>C/ p.Arg51Pro and c.155T>G/ p.Phe52Cys. Mice engineered to carry the p.Arg51Leu change showed a highly-penetrant optic disc anomaly in heterozygous animals with severe microphthalmia in homozygotes.

PMID:36446583 (2023) reported the identification of a novel missense variant (p.Phe52Leu) in a three-generation pedigree with autosomal dominant microphthalmia.

PMID:36892533 (2023) reported the identification of three heterozygous missense variants in MAB21L1 gene in five unrelated families, including c.152G>T/ p.Arg51Leu in two, c.152G>A/ p.Arg51Gln in two, and c.155T>G/ p.Phe52Cys in one. All patients presented with similar blepharophimosis plus anterior segment and macular dysgenesis (BAMD) phenotype.

PMID:39016008 (2024) reported an additional family with four individuals diagnosed with microphthalmia and with Arg51 variant in MAB21L1 gene.; Changed publications: 30487245, 39016008, 36892533, 36446583, 36413568; Changed phenotypes: Cerebellar, ocular, craniofacial, and genital syndrome OMIM#618479, Microphthalmia MONDO:0021129, MAB21L1-related
