The c.1041T>G (p.F347L) alteration is located in exon 1 (coding exon 1) of the ITPRIPL1 gene. This alteration results from a T to G substitution at nucleotide position 1041, causing the phenylalanine (F) at amino acid position 347 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
