The c.353T>A (p.L118Q) alteration is located in exon 1 (coding exon 1) of the FAM83A gene. This alteration results from a T to A substitution at nucleotide position 353, causing the leucine (L) at amino acid position 118 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
