The c.425T>A (p.L142H) alteration is located in exon 1 (coding exon 1) of the RSBN1L gene. This alteration results from a T to A substitution at nucleotide position 425, causing the leucine (L) at amino acid position 142 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
