The c.553G>A (p.A185T) alteration is located in exon 6 (coding exon 5) of the FAM168A gene. This alteration results from a G to A substitution at nucleotide position 553, causing the alanine (A) at amino acid position 185 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
