The c.2232C>A (p.H744Q) alteration is located in exon 10 (coding exon 10) of the FAM184A gene. This alteration results from a C to A substitution at nucleotide position 2232, causing the histidine (H) at amino acid position 744 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
