The c.104C>T (p.T35I) alteration is located in exon 2 (coding exon 1) of the RABGAP1 gene. This alteration results from a C to T substitution at nucleotide position 104, causing the threonine (T) at amino acid position 35 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
