The c.578G>A (p.R193Q) alteration is located in exon 5 (coding exon 4) of the TBCEL gene. This alteration results from a G to A substitution at nucleotide position 578, causing the arginine (R) at amino acid position 193 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
