Congenital heart diseases (CHDs) are the most common of all birth defects and one of the leading causes of mortality in the fi rst year of life. CFC1 gene is a cell signaling protein and it is a co-receptor in nodal signaling pathway and involve in right and left axis determination during gastrulation. Th is is a case control study, recruited 175 non syndromic patients and 140 controls, healthy unrelated individuals. Th e study aft er formal approval includes patients from various pediatric cardiology centers in three years. A detailed family history was taken to elucidate the genetic and environmental factors. Pediatric cardiologist confi rmed the diagnosis on the basis of all standard testing like chest X-ray, CBC, ECG, ECHO, heart murmur, cardiac catherization reports etc. DNA extraction and sequencing was done and data was interpreted by multiple sequence alignment soft ware. Statistical data was done by SPSS 17.0. Th e mean age for controls was 3.14±1.82 years for TOF; 2.97±1.21 and for DTGA patients 1.84±2.26 years. TOF and DTGA were frequent in males. Th e study demonstrates frequency of this disease with its variation in Pakistani population. Consanguinity aff ects the rate of CHDs as it is 62% in patients and 25% in controls. Two novel mutations were found in CFC 1 gene. Th e study reveals frequency and prevalence for TOF and DTGA, their variation and association with other cardiac defects. CFC1 and its mutations may play a key role in cardiac malformation.
