Genes affected
C12orf57 (HGNC:29521): (chromosome 12 open reading frame 57) This gene is ubiquitously expressed in human tissues. It is required for development of the human corpus callosum. Mutations in this gene are associated with Temtamy syndrome (TEMTYS). Multiple alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Sep 2014]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -14 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.56).
BP6
Variant 12-6945781-G-A is Benign according to our data. Variant chr12-6945781-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 210547.We mark this variant Likely_benign, oryginal submissions are: {Benign=1, Uncertain_significance=1}.
BP7
Synonymous conserved (PhyloP=2.36 with no splicing effect.
BS1
Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.000138 (202/1461492) while in subpopulation SAS AF= 0.00221 (190/86116). AF 95% confidence interval is 0.00195. There are 2 homozygotes in gnomad4_exome. There are 154 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High Homozygotes in GnomAdExome4 at 2 AR gene
