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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 13, 2024The c.544A>G (p.S182G) alteration is located in exon 7 (coding exon 7) of the FAM9B gene. This alteration results from a A to G substitution at nucleotide position 544, causing the serine (S) at amino acid position 182 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
