The c.2189A>T (p.K730I) alteration is located in exon 1 (coding exon 1) of the LRRC37A gene. This alteration results from a A to T substitution at nucleotide position 2189, causing the lysine (K) at amino acid position 730 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
