The c.739C>T (p.R247C) alteration is located in exon 7 (coding exon 6) of the SH2D4A gene. This alteration results from a C to T substitution at nucleotide position 739, causing the arginine (R) at amino acid position 247 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
