| Fetal anomalies v1.124 | INTS13 |
Chirag Patel gene: INTS13 was added gene: INTS13 was added to Fetal anomalies. Sources: Literature Mode of inheritance for gene: INTS13 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: INTS13 were set to PMID: 36229431 Phenotypes for gene: INTS13 were set to Oral-facial-digital syndrome Review for gene: INTS13 was set to GREEN gene: INTS13 was marked as current diagnostic Added comment: 2 families with 4 affected individuals with Oral-facial-digital (OFD) phenotype. Homozygosity mapping and WES found 2 homozygous variants in INTS13 gene. This is a subunit of the Integrator complex, which associates with RNA Polymerase II and cleaves nascent RNA to modulate gene expression. Variants segregated with disease. Depletion of INTS13 disrupts ciliogenesis in human cultured cells and causes dysregulation of a broad collection of ciliary genes. Knockdown in Xenopus embryos leads to motile cilia anomalies.

| Fetal anomalies v1.13 | TNNI1 |
Krithika Murali gene: TNNI1 was added gene: TNNI1 was added to Fetal anomalies. Sources: Literature Mode of inheritance for gene: TNNI1 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: TNNI1 were set to 34934811 Phenotypes for gene: TNNI1 were set to arthrogryposis; joint contractures Review for gene: TNNI1 was set to AMBER Added comment: No OMIM gene disease association reported PMID 34934811 Nishimori et al report 2 individuals from a Japanese family with joint contractures, elevated CK and a novel heterozygous TNNI1 variant. The proband was born with clasped thumbs (gestational age not stated) requiring surgical correction at 5 months of age. At age 14 was diagnosed with contractures of the neck, trunk, hip and knee with elevated serum CK (1689 IU/L). No muscle weakness noted. Muscle biopsy showed moth-eaten appearance of type I fibres and electron microscopy showed type 1 fibre Z disk streaming. Trio exome sequencing identified a paternally heterozygous nonsense TNNI1 variant (c.523A>T p.K175*). The proband's father and paternal grandfather (not genotyped) also have a history of joint contractures with elevated CK. The affected amino acid residue is in the tropomyosin binding site near the C-terminus and is highly conserved. The variant is absent from gnomAD. rt-PCR products of mRNA from the patient's muscle biopsy showed presence of both mutated and normal transcripts. Sources: Literature |

| Fetal anomalies v0.4317 | TUBGCP2 |
Chirag Patel gene: TUBGCP2 was added gene: TUBGCP2 was added to Fetal anomalies. Sources: Expert list Mode of inheritance for gene: TUBGCP2 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: TUBGCP2 were set to PMID: 31630790 Phenotypes for gene: TUBGCP2 were set to Pachygyria, microcephaly, developmental delay, and dysmorphic facies, with or without seizures, OMIM # 618737 Review for gene: TUBGCP2 was set to GREEN Added comment: Pachygyria, microcephaly, developmental delay, and dysmorphic facies, with or without seizures (PAMDDFS) is an autosomal recessive neurologic disorder characterized by progressive microcephaly associated with abnormal facial features, hypotonia, and variable global developmental delay with impaired intellectual development. Brain imaging shows variable malformation of cortical development on the lissencephaly spectrum, mainly pachygyria and thin corpus callosum. 4 unrelated patients with homozygous or compound heterozygous mutations in the TUBGCP2 gene, found by WES and segregated with the disorder in all families. Functional studies of the variants were not performed, but analysis of patient fibroblasts derived from the patient with a splice site mutation demonstrated the production of several abnormal transcripts that were predicted to result in a loss of function.
