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]

FAM186B links:

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]

Ambry Genetics

Nov 09, 2023

The c.2359C>G (p.P787A) alteration is located in exon 5 (coding exon 5) of the FAM186B gene. This alteration results from a C to G substitution at nucleotide position 2359, causing the proline (P) at amino acid position 787 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
