The c.438G>T (p.Q146H) alteration is located in exon 5 (coding exon 5) of the RCSD1 gene. This alteration results from a G to T substitution at nucleotide position 438, causing the glutamine (Q) at amino acid position 146 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
