Genes affected

FAM53C (HGNC:1336): (family with sequence similarity 53 member C) The protein encoded by this gene belongs to the FAM53 protein family. FAM53 protein family members bind to a transcriptional regulator that modulates cell proliferation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2017]

The c.244A>G (p.S82G) alteration is located in exon 4 (coding exon 3) of the FAM53C gene. This alteration results from a A to G substitution at nucleotide position 244, causing the serine (S) at amino acid position 82 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
