Sep 14, 2022

The c.496T>C (p.Y166H) alteration is located in exon 6 (coding exon 6) of the FAM206A gene. This alteration results from a T to C substitution at nucleotide position 496, causing the tyrosine (Y) at amino acid position 166 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
