Genes affected
FAM50B (HGNC:18789): (family with sequence similarity 50 member B) This gene contains an intronless ORF that arose from ancestral retroposition. The encoded protein is related to a plant protein that plays a role in the circadian clock. This gene is adjacent to a differentially methylated region (DMR) and is imprinted and paternally expressed in many tissues. [provided by RefSeq, Nov 2015]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 21, 2023The c.602T>G (p.V201G) alteration is located in exon 2 (coding exon 1) of the FAM50B gene. This alteration results from a T to G substitution at nucleotide position 602, causing the valine (V) at amino acid position 201 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
