Collection Method: clinical testing

The c.991A>T (p.S331C) alteration is located in exon 1 (coding exon 1) of the ITPRIPL2 gene. This alteration results from a A to T substitution at nucleotide position 991, causing the serine (S) at amino acid position 331 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
