Genes affected

SLC25A12 (HGNC:10982): (solute carrier family 25 member 12) This gene encodes a calcium-binding mitochondrial carrier protein. The encoded protein localizes to the mitochondria and is involved in the exchange of aspartate for glutamate across the inner mitochondrial membrane. Polymorphisms in this gene may be associated with autism, and mutations in this gene may also be a cause of global cerebral hypomyelination. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, Apr 2012]

SLC25A12 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0021488369).
• BP6: Variant 2-171793655-C-T is Benign according to our data. Variant chr2-171793655-C-T is described in ClinVar as [Benign]. Clinvar id is 332339.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.031 (4723/152234) while in subpopulation NFE AF= 0.0461 (3137/68020). AF 95% confidence interval is 0.0448. There are 104 homozygotes in gnomad4. There are 2291 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 104 AR gene
