The c.404C>T (p.T135I) alteration is located in exon 4 (coding exon 3) of the LRRC31 gene. This alteration results from a C to T substitution at nucleotide position 404, causing the threonine (T) at amino acid position 135 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
