Collection Method: clinical testing

The c.3494A>G (p.Y1165C) alteration is located in exon 21 (coding exon 20) of the IGSF22 gene. This alteration results from a A to G substitution at nucleotide position 3494, causing the tyrosine (Y) at amino acid position 1165 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
