The c.2065A>T (p.N689Y) alteration is located in exon 24 (coding exon 23) of the SLC44A5 gene. This alteration results from a A to T substitution at nucleotide position 2065, causing the asparagine (N) at amino acid position 689 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
