The c.4805T>C (p.I1602T) alteration is located in exon 12 (coding exon 10) of the LRRC37A3 gene. This alteration results from a T to C substitution at nucleotide position 4805, causing the isoleucine (I) at amino acid position 1602 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
