Genes affected
MID1 (HGNC:7095): (midline 1) The protein encoded by this gene is a member of the tripartite motif (TRIM) family, also known as the 'RING-B box-coiled coil' (RBCC) subgroup of RING finger proteins. The TRIM motif includes three zinc-binding domains, a RING, a B-box type 1 and a B-box type 2, and a coiled-coil region. This protein forms homodimers which associate with microtubules in the cytoplasm. The protein is likely involved in the formation of multiprotein structures acting as anchor points to microtubules. Mutations in this gene have been associated with the X-linked form of Opitz syndrome, which is characterized by midline abnormalities such as cleft lip, laryngeal cleft, heart defects, hypospadias, and agenesis of the corpus callosum. This gene was also the first example of a gene subject to X inactivation in human while escaping it in mouse. Alternative promoter use, alternative splicing and alternative polyadenylation result in multiple transcript variants that have different tissue specificities. [provided by RefSeq, Dec 2016]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -13 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.0066638887).
BP6
Variant X-10449372-G-A is Benign according to our data. Variant chrX-10449372-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 92878.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=1, Benign=5}. Variant chrX-10449372-G-A is described in Lovd as [Benign].
BS1
Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.00266 (297/111682) while in subpopulation AMR AF= 0.022 (232/10531). AF 95% confidence interval is 0.0197. There are 2 homozygotes in gnomad4. There are 112 alleles in male gnomad4 subpopulation. Median coverage is 23. This position pass quality control queck.
BS2
High Homozygotes in GnomAd4 at 2 XL gene
