Genes affected

FAM9B (HGNC:18404): (family with sequence similarity 9 member B) This gene is a member of a gene family which arose through duplication on the X chromosome. The encoded protein may be localized to the nucleus as the protein contains several nuclear localization signals, and has similarity to a synaptonemal complex protein. [provided by RefSeq, Aug 2011]

The c.515T>G (p.L172R) alteration is located in exon 7 (coding exon 7) of the FAM9B gene. This alteration results from a T to G substitution at nucleotide position 515, causing the leucine (L) at amino acid position 172 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
