Genes affected
FAM186B (HGNC:25296): (family with sequence similarity 186 member B) This gene product is a member of the FAM186 family, however, its exact function is not known. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Sep 2009]
PRPF40B (HGNC:25031): (pre-mRNA processing factor 40 homolog B) This gene encodes a WW-domain containing protein similar to yeast splicing factor PRP40. This protein has been shown to interact with Huntingtin and methyl CpG binding protein 2 (MeCP2). Alternative splicing results in different transcript variants. [provided by RefSeq, Aug 2014]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -14 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.0029908419).
BP6
Variant 12-49588455-G-A is Benign according to our data. Variant chr12-49588455-G-A is described in ClinVar as Benign. ClinVar VariationId is 1601350.Status of the report is criteria_provided_single_submitter, 1 stars.
BS1
Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.00119 (181/152318) while in subpopulation EAS AF = 0.0295 (153/5194). AF 95% confidence interval is 0.0257. There are 4 homozygotes in GnomAd4. There are 89 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High Homozygotes in GnomAd4 at 4 AR gene
