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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 06, 2023The c.2294C>T (p.T765M) alteration is located in exon 5 (coding exon 5) of the FAM186B gene. This alteration results from a C to T substitution at nucleotide position 2294, causing the threonine (T) at amino acid position 765 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
