The c.22A>T (p.N8Y) alteration is located in exon 4 (coding exon 1) of the FAM149A gene. This alteration results from a A to T substitution at nucleotide position 22, causing the asparagine (N) at amino acid position 8 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
