The c.698C>T (p.A233V) alteration is located in exon 2 (coding exon 1) of the FAM110D gene. This alteration results from a C to T substitution at nucleotide position 698, causing the alanine (A) at amino acid position 233 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
